Meet Dan and Phil. The boys are roommates at university, Phil being the quiet one with stage freight and Dan is the loud, outgoing one. Phil prefers his books. Dan prefers his band. Phil is good in school. Dan is good at beer pong. The two are completely different and rarely communicate, so when the lead singer of Dan's band drops out, he becomes desperate and has heard Phil singing one too many times. Then suddenly Phil is a part of the band and they're sleeping in a bus on a worldwide tour. [rated R for drug/alcohol use, sexual references and language]
