When heroic, charming and handsome Sir Galavant loses his true love, the beautiful Madalena, to evil King Richard's wealth and power, he falls into a deep and drunken despair. Just as our hero hits rock bottom, Princess Isabella shows up with a quest to save her kingdom, defeat the despicable King Richard, and provide an opportunity for Galavant to reclaim Madalena. Galavant is off to become a hero again and strike a blow for true love…but first, Galavant has to fit into his old hero pants.

Galavant enters a jousting tournament against a boastful rival, Sir Jean Hamm, to test his return to heroic form (and win some much-needed traveling money and a really nice rooster). But it quickly becomes clear that Galavant is a long shot to win. Meanwhile, King Richard asks Gareth to help him become a bit more macho so that Madalena won't despise him quite so much.

A visit to Sid's hometown reveals he has not been truthful about his career path. While Galavant and Isabella back up Sid's stories, King Richard decides to throw a ball to cheer up the people of Valencia.

An encounter with land-bound pirates forces Galavant, Isabella and Sid to learn how to get over their petty squabbles and work together. Meanwhile, King Richard tries a new tact to win Madalena's love.

As our heroic trio finally approaches Valencia, they find shelter and doo-wop among local monks who have taken a vow of singing, led by Confessional Monk. Madalena, frustrated with King Richard, decides to take matters into her own hands with her own devious plot involving the besotted Chef and her winsome handmaiden, Gwynne.

While Galavant struggles with the realization about his true love, King Richard goes on a voyage of self-discovery, thanks to a potion from the magician, Xanax. As Galavant draws closer to the woman he really loves, an emboldened King Richard starts to assert himself, just as his meaner, elder brother returns—Kingsley.

Thinking about being in a relationship, Isabella wants Galavant to try to impress her parents with attentive small talk, but he’s confident that breaking everyone out of prison will impress them and save them from certain death. Galavant gets his opportunity for a hero moment when King Richard challenges his brother to a duel and needs a champion to fight for him.

Galavant enlists King Richard in a plot to kill Kingsley before the duel… but ends with a drunken whimper. Will Gareth kill King Richard in the duel? Will Galavant rescue everyone? Will Madalena find a new “boy toy?” The answers are very different from what you expect.

Bad advice results in Galavant and the crew being shipwrecked, and they end up traveling by foot in order to get back to Richard’s kingdom. Later, Galavant and King Richard find themselves at The Enchanted Forest Pub in West Hollow-wood where they are forced into working there by the owner who sees Galavant in a different light.

Meanwhile in Valencia, Madalena rules as Queen, and Gareth demands his due when he is announced as King, with Sid as his assistant. Elsewhere in Hortensia, Isabella is imprisoned in her jewel box by her 12-year-old cousin as her parents prepare for their wedding.

Galavant and Richard see a fortune teller who is able to connect Galavant to Isabella using a crystal ball. Isabella receives Galavant's "call" as she is plotting her escape from Hortensia. Unfortunately, it's a "bad connection," and Isabella hears only every other word. She is devastated by the call, but Galavant believes it went well. He promises to return to her as soon as he drops Richard off at his castle. The only problem is that Richard's castle seems to have disappeared.

While continuing their quest to gather an army, King Richard discovers that he has a connection to Roberta, the beautiful warrior who volunteered to help. Galavant plays matchmaker. Madalena is invited to the Basikobitcz party - the "it" girls of the kingdom - and can't wait to be accepted into their group. The party is not what she expected, and, when she returns home, she discovers that she has feelings and does not like her new emotion. Gareth cheers her up with a present while Chef tries to convince Gwen that their lives are better in Hortencia. Under Wormwood's spell, Isabella is in full wedding-planning mode.

In their war against Valencia, all hope seems lost for Isabella and the people of Hortensia until Galavant arrives with his zombie army.

Meanwhile, Gareth abandons Madalena after he realizes that she betrayed him and is learning (and using) the Dark Dark Evil Way.

Under Madalena and Wormwood's spell, the zombie army revolt against Galavant and company, until Sid arrives with an unlikely army of his own. Galavant, Gareth, and Sid's army battle the Zombies while Isabella fights Madalena.

Meanwhile, Richard goes after Wormwood, who attacks Tad Cooper, which provokes Richard to perform a (nearly) heroic act. Elsewhere, Gareth tries to reason with Madalena, but she is driven to learn how to use her newly acquired dark magic. At the end of the day, who will get their happily ever after?
