The Venjix Computer Network is attempting to conquer and lay ruin to the entire planet, and the human race has retreated into the environmentally shielded domed city of Corinth to protect itself from destruction. There, an elite force of Rangers is assembled in order to protect the city and battle the attacking machine army bent on world domination.

As Venjix grows stronger, it becomes clear that the Rangers need more than three operators to defend the city. Summer suggests that Dillon be the new Black Ranger, but with him part-machine and part-human, no one knows what side he's really on.

Dillon goes through a series of tests to see if he even is Ranger material, but the real test comes when he is faced with the choice of seeking out his past or helping the Rangers as promised.

When Ziggy is charged with finding the new Green Ranger, he finds the perfect candidate in Tenaya 7, until he realizes she's a machine working for Venjix!

Ziggy's recruitment as Ranger Green is put into question when parts of his shady past are revealed. Should the Rangers work with someone who is hated by all seven of Corinth's cartels?

Scott is flooded with memories of his brother when he returns to Marcus' crash site in order to retrieve an over thruster core the Rangers need for the new Megazord configuration.

Mr. & Mrs. Landsdown suddenly reappear in Summer's life, intent on making their daughter live up to her promise to marry into a wealthy family. Once married, Summer will receive the black diamond, the family heirloom that Venjix plans on using to bring destruction to Corinth.

Diamonds and pretty dresses are no longer important to Summer, who finds her true meaning in what she does with the Rangers.

A malfunction in his Time Manipulation Burst causes Flynn to be sidelined as the other Rangers face off against Tenaya 7 and her Grinders. While waiting for Doctor K to come up with a solution, Flynn looks back on his life leading up to Venjix's attack and how he came to be the Blue Ranger.

While attempting to overcome a power problem with the Rangers' new zord configuration, Doctor K is haunted by memories of her childhood being held at the "Alphabet Soup" think tank and a terrible mistake for which she has tried to make up for.

Dillon has a dream about his past when the Rangers are called into action. Venjix sends multiple monsters, wearing the Rangers down, and Dillon must make an important decision when he confronts the monster that has his stolen memories. He decides to keep his new memories and forget everything.

Tenaya 7 implants a remote device on Dillon's back of his neck which makes him fall under the control of Venjix and makes his bionic implants begin to take over his body. When he tries to leave the city, Dillon finds himself chained by Scott, leaving the rest of the Rangers to seek out the means to help him.

Dillon seeks to find more about his past by traveling to Omega City with the other Rangers in the GO-ONGER vehicle. They are sidetracked when Venjix downloads himself into a Generation 13 Attack Bot. When things look bad for the Rangers, two new and unknown Rangers appear to help. They then disappear, leaving the five Rangers in wonder of their identities.

The Rangers arrive at Omega City only to discover it was all a trap set by Venjix. In the midst of trying to escape, they are ambushed and overwhelmed by Venjix forces, but are saved by Rangers Gold and Silver who, this time, fight off their assailants in person. The seven Rangers then return to Corinth, where Rangers Gold and Silver finally reveal themselves as Gem and Gemma, long lost friends of Dr. K from the Alphabet Soup facility.

Scott decides to join Gem and Gemma in a more offensive approach in the battle against Venjix. Colonel Truman defaults to his usual "defend the city" tactics and ends up trapping everyone inside while a Venjix bot sucks all the air out of the city. The remaining Rangers make a deadly escape from Corinth and regroup with Scott in order to save the city.

Dillon hears Gem & Gemma humming a tune identical to the one from his pocket watch. They inform him that they learned it from a blind girl they befriended in a Venjix work camp, and that the tune came from a pocketwatch belonging to the girl's brother Dillon, convinced that his sister is still there, mounts a rescue attempt with the help of Summer and Ziggy while Scott and Flynn attempt to hold off a dangerous new attack bot. Dr. K and the Rangers learn that Venjix is building a doomsday weapon, and must venture back to the facility to destroy it.

The Rangers must return to the factory where the doomsday device is being built. Dillon attempts to find his sister before it's too late. Dillon discovers that he, Summer, Gem & Gemma are in his sister's cell. Summer finds the key that belonged to Dillon's sister at Venjix factory that matches Dillon's key.

Gem & Gemma's "blow things up and ask questions later" motto is getting quite out of hand. They follow a trail they think might lead to the Venjix Palace and end up walking right into a trap. They must learn to work together with the other Rangers as a team and in turn form a new Megazord configuration called the SkyRev Megazord.

In an effort to impress his father, Scott makes a reckless trip out to the wasteland. He and Gem stumble upon human prisoners and their field trip turns into a rescue mission. Venjix test-drives his new and improved robotic form. His new body doesn't hold up very well against the Rangers. Scott talks to Dillon about the Venjix Prisoners Camp where humans are infected with the Venjix virus, and Grinders make human hybrids like Dillon, his sister & the other at the Venjix Palace.

For the first time, Gem and Gemma split up on something. Gemma believes in what Flynn can do. Together, they work on a wheelzord on the side. With all their resources used up, Dr. K has to trust the untested technology and they use it to destroy the latest attack bot.

A Chemical Attack Bot attacks the city and puts all men fast asleep. Now, the women of Corinth, led by Summer, all have to work together and save the day. Dr. K works on an antidote to awaken the men of Corinth City.

For the first time ever join Ziggy as he takes you behind the scenes & bloopers of Power Rangers. See how explosions and stunts are really done, as well as the funny moments that don’t make it into the episode, but keep the Power Ranger set a lively place to work as a Ranger. The Rangers & Dr. K are sitting on the couch to watch their episode.

Untested technology is found in an Alphabet Soup dumping ground. Colonel Truman tries to keep the technology from Venjix and comes across a video log that pins Dr. K responsible for the start of Venjix. Colonel Truman wants to arrest Dr. K. but if he does, then she wouldn’t be able to help the Rangers with the dangerous Paleomax technology.

It dawns on Dillon that the two keys to his musical pocketwatch fit together to play another tune -- the same one that Tenaya 7 whistles. Tenaya 7 is hit by memories of her past. She does some investigating on her own and finds out what really happened to her. Dillon finds out Tenaya 7 is his long lost sister.

Tenaya 7 & Dillon go to Venjix palace to retrieve codes to stop an Attack Bot. Dillon is left wondering which side she is on when she turns him into Venjix. With the stolen codes, Dr. K is able to configure the RPM Ultrazord. Kilobyte captures Tenaya 7 before she can reunite with the Rangers.

Dillon's search for Tenaya is put on hold when Scott is in trouble. Scott was shot with a key that allows Shifter to control him. The Rangers do their best to save their leader when they come face to face with Tenaya 15. She has been reprogrammed with one mission: Serve Venjix. Dr. K makes a gun whose shots can make Tenaya susceptible to mind control.

It's time for Ziggy to pay back the $5 million he owes Fresno Bob. Tenaya 15 makes a deal with Fresno Bob to give him Ziggy in exchange for a certain case. Instead, she double-crosses Fresno Bob and Ziggy ends up saving him. The Rangers deploy Dr. K's Rail Saber weapon against the latest Attack Bot. Fresno Bob and Ziggy are now even.

Ziggy and Doctor K are accidentally teleported into a distant cave outside of Corinth. The remaining Rangers need to find out the password to Dr. K's computer and retrieve them, but their efforts instead triggers a time capsule recording compiled by Dr K, to be played only if Venjix attained absolute victory.

Venjix’s end game is about to reveal itself. Every Attack Bot has been a calculating step closer to his plan. The city is filled with hybrids just like Dillon. Venjix is going to activate them all and Corinth will be brought down.

When the magnetic blast goes off and all the electricity goes out in Corinth, Venjix moves to take the city.

The Rangers race to insert a virus into Venjix before he takes over Corinth.
