After his dad runs off with a young real estate agent, Tucker and his unemployed mom, Jeannie, are forced to move in with his tyrannical aunt, Claire, his goofy uncle, Jimmy, and their immature son, Leon. While forced to suffer through Leon's unwelcome wrestling moves and Claire's unfounded accusations of peeping on her, Tucker finds some consolation in his new living arrangements when he meets the hot girl next door, McKenna.

Tucker tries to buddy up to Kenickie, a classmate he thinks is dating McKenna, in an effort to put a wedge between them -- only to discover later that McKenna is actually dating Seth Green. Meanwhile, Claire schemes to monitor what Jeannie spends by getting her sister to sign up for an account at her bank.
