Life is sweet for 35-year-old video game tester Alex (Allen Covert), until he's forced to move in with his overbearing grandmother Lilly (Doris Roberts) and her two roommates: oversexed Grace (Shirley Jones) and overmedicated Bea (Shirley Knight). To save face with his much younger co-workers and super-sexy new boss (Linda Cardellini), Alex brags about the "three hot babes" living with him, but soon that cat's out of the bag - and the real party at Grandma's house has just begun!
