When sixteen-year-old Jess arrives on foster carer Maggie Hartley's doorstep with her newborn son Jimmy, she has nowhere else to go.

Arriving straight from the hospital having just given birth, Jess is like a rabbit caught in the headlights. Scared, alone, and practically a child herself, she is overwhelmed with the responsibility of caring for a newborn without the support of a loving family or her beloved boyfriend. With social services threatening to take baby Jimmy into care, Jess knows that Maggie is her only chance of keeping her son.

Maggie can see that Jess loves her boyfriend and wants to be a good mother to her son. Can Maggie help Jess learn to become a mum? Will the family ever be allowed to live together?
