After pitching several spring dance theme ideas, Andrew decides to go with Symphony in Space: The Final Dance frontier. Andrew works feverishly to put the dance together and has recruited Sarah to assist him. Meanwhile, Drew brags to Alan and Andrew that he'll have the most beautiful date at the dance, Anastasia, who just finished modeling in Europe. Alan and Andrew don't believe him, poking fun at his imaginary girlfriend. Andrew's too busy to have a date while Alan decides to fly solo. Mariah ends up with two dates while Shaylen jumps at her first offer and agrees to go with Egbert, who suffers from terrible allergies. At the dance, Andrew, dressed as an astronaut, welcomes everyone to the dance. Drew shows up alone, saying Anastasia's running late, but his friends still don't believe him. Mariah arrives with her two dates, who fight over who gets to take her jacket and who can get her punch. Shaylen arrives with Egbert, who's decked out in a lime green tuxedo. Everything seems to be going well until Mr. Pesckow informs Andrew that he forgot to book a band. Panicked, Mr. Peskow plays his accordion to the audience, but ends up storming out of the dance after getting booed off the stage. Andrew has an idea, ties the door shut to lock Mr. Pesckow out, and convinces the gang that they need to perform. The gang finally agrees, especially Mariah and Shaylen, who are desperate to get away from their dates. The gang rocks out to wild applause while Mr. Pesckow tries desperately to get back into the dance, demanding to know what's going on. He eventually gets back in, but can't figure out who performed. The dance is a success.
