Andy's girlfriend Polly is planning to spend Christmas at her grandmother's, which puts a kink in his plans to take her to the country club Christmas party. He agrees (for a fee) to pretend to be the boyfriend of his buddy Beezy's girl Cynthia to discourage other suitors (Beezy is also leaving for the holidays), but Andy soon finds her too infatuated with him. Meanwhile, Andy's next door neighbor Betsy begins to fall in love with Andy even though she's younger than him. Everything comes to a head at the country club party.
