Lisa Darling, a high-powered TV executive and twice-divorced mother of two, is navigating life with an opinionated teenager and a pet-obsessed grade-schooler, organizing PTA events, and supporting her best friend through breast cancer treatment.

As things snowball, Lisa has to ask herself what she really wants.
