Fifteen-year-old Jess arrives at the home of foster mother Maggie Hartley straight from the hospital where she's given birth to her son, Jimmy. Scared and alone, Jess is like a rabbit caught in the headlights. Unable to live with her own mother, a prostitute, and removed from the home of her childhood sweetheart, Darren, Jess is overwhelmed by the responsibility of caring for a newborn whilst still little more than a child herself.
Maggie knows that Jess is desperate to reunite with Darren and to be a good mum to their son. Can Maggie help Jess keep her baby, and will the family ever be able to live together again?
