The four Elements arrive at the Cosmic Compound and meet a group of eligible singles. They each go on a first date before any of their ideal matches are revealed; some follow their astrological advice, and some fall back into old patterns. Sparks begin to fly and early connections are tested when each Element has their first match revealed.

Things get messy as the Elements forge new bonds during a group activity. Maria struggles to follow the advice of the Astro Chamber, and the pressure of the experiment begins to overwhelm firefighter Connor. Each Element discovers another one of their matches and then tempers flare at a beach party when Phoebe finds out she’s been misled.

The Astro Chamber continues to deliver guidance while other connections in the compound cause some of the Elements to rethink their matches. Noel deals with balancing his many connections, while Phoebe looks for at least one. Maria gets upsetting news but then bounces back when an unexpected match is revealed and takes her by surprise.

Phoebe dishes out some hard truths which leads to a confrontation with Phil, while one of Maria’s matches makes a push for her attention. Then, with tensions already high, the Elements find out their fourth and final matches. Not everyone at the Cosmic Compound is happy with who is matched with who, especially Chris R.

Now that the elements know all four of their matches, they get a chance to know them even better… on a group date. Phoebe lets her matches know that romance is back on the table, before the Astro Chamber drops a bombshell that leaves all of the Elements reeling.

Maria makes her decision and the entire compound is left in shock. Noel and Maria take their relationships to the next level, while Connor continues to be stuck in first gear. A group activity triggers a surprising emotional moment, and Phoebe makes a last-ditch attempt to take the Astro Chamber’s advice but is blindsided by betrayal.

It’s time for the Elements to decide which of their matches they want to get engaged to, but first they are surprised by a new presence in the Astro Chamber. As proposals loom, Noel's connection with his newest match continues to grow, Maria considers her options, and Connor faces his biggest fear… having to make a monumental decision?

The final proposals lead to more dramatic moments, and then the remaining Elements help their fiancés move in with them. As the adrenaline rush of the engagements fades, the Elements and their partners wrestle with the reality of their situation, how well they really know each other, and what they want out of their recently established relationships.

With weddings looming it’s time for the Elements and their fiancés to meet each other’s families. The Astro Chamber doles out advice on how to make the best first impression, but will Astrology be enough to convince their future in-laws that they are ready for marriage? In the final hour, Connor has to make his decision.
