Twenty-somethings Mike and Mia have been dating but haven't had sex yet. When Mia tells Mike she'd like to say over, Mike is reluctant since she doesn't know that that he still lives with his conservative, domineering mother. He agrees, warning that he has a very neurotic roommate that cannot be disturbed. Will Mike sneak Mia back into his room successfully? Of course not. Will awkwardness and embarrassment ensue? Definitely. How many more secrets will be exposed in one night? Mum's the word.
