Nervous about starting college and disappointed that her dorm roommate has not arrived yet, Sue begins to drive Frankie and Mike crazy with her multiple texts and calls at all hours. But when her dorm roommate finally arrives, Sue naively thinks that all of her worries are going to go away and that she'll make a new life-long friend. Meanwhile, Axl and Hutch find their house being overrun by ants, and Brick finds himself being protected by his own mysterious school bodyguard.

Frankie is completely gobsmacked when Mike's brother Rusty (Norm Macdonald) pays an unexpected visit and offers him an opportunity to partner on one of his crazy business ideas -- and Mike wants in. Meanwhile, Axl goes to extreme measures to prove to Mike that he can handle riding his dad's new motorcycle; and unbeknownst to her parents, Sue tells Brad that her college roommate is so horrible that she's resorted to living in her car.
