What are the first names of the people who resort to playing in dive bars?
Hooter College student Chuck has decided academics aren't going to get him anywhere in life, so he's taken to managing a band his classmates have formed called The Splitz, which consists of lead singer Joan, guitarist Gina and drummer Susie.  The Splitz struggle to make a name for themselves and resort to playing in dive bars where the patrons are more interested in boozing and brawling than appreciating the music.
The day after a disastrous show, Chuck escorts Gina to her home, where he meets her former-mobster father, who becomes obsessed with the percentage of the band's income that Chuck is claiming.  Chuck also meets Gina's cousin Vinnie,  a sweet but oversexed meathead who can't score a date, so Chuck encourages him to try hypnosis.
Meanwhile, the evil Dean Hunta informs the heads of three sororities that they'll have to compete in a trio of events to determine who's going to lose their house to make way for a new sewage treatment plant.  The dean favors Sigma Phi's Lois Scagliani and Delta Phi's Fern Hymenstein and informs them that the Phi Betas have to lose.  When asked if she has an axe to grind with the Phi Beta sorority, the Dean replies that it's "just another act of random, senseless violence perpetrated against the underdogs."
At the first competition, a soccer game, Gina is disgusted to see the way that Phi Beta's Midge and her peers are being trampled by their competitors, so she gets into the game herself and the other Splitz quickly follow suit.   Although the Phi Betas lose the game, they gain an all-girl rock band, who immediately become part of their sorority.
