Jackie is a divorced mother of two. Isabel is the career minded girlfriend of Jackie’s ex-husband Luke, forced into the role of unwelcome stepmother to their children. But when Jackie discovers she is ill, both women realise they must put aside their differences to find a common ground and celebrate life to the fullest, while they have the chance.
