Martini Mondays and tequila Tuesdays take a back seat to new step-motherhood when former party girl Stephanie marries Charlie, an older dad with three kids. Becoming an instant mom doesn’t come with a rulebook, but it does come with a dose of humor as Stephanie traverses the fine line between being a friend and being a responsible parent.

The story of David Hobbs, who has spent the last decade playing the perfect father on one of TV’s biggest sitcoms. But when the series ends and his wife resumes her own television career, he finds himself cast in his most challenging role to date: handling the day-to-day needs of three kids who’ve grown accustomed to not having him around. David soon learns that playing a dad on TV is child’s play compared to the real thing.
