Tracy Waterhouse leads a quiet, ordered life as a retired police detective -- a life that takes a surprising turn when she encounters Kelly Cross, a habitual offender, dragging a young child through town. Both appear miserable and better off without each other -- or so decides Tracy, in a snap decision that surprises herself as much as Kelly. Suddenly burdened with a small child, Tracy soon learns her parental inexperience is actually the least of her problems, as much larger ones loom for her and her young charge.
