But when their mother is diagnosed with cancer, Ava's prodigal little sister Lauren comes home to Los Angeles where she stumbles across the decades-old document.Frustrated and embarrassed by Ava's constant lectures about financial responsibility (all because she's in a little debt.

When she finds him, the highly inappropriate, twice-divorced, but incredibly charming Russell Markowitz is all too happy to re-enter the Nickerson sisters' lives, and always-accountable Ava is forced to consider just how binding a contract really is . . .
