The Kid with a Bike

At about 11, the stubborn and impulsive Cyril seems on his way to delinquency: he has no mother, his father wants a new life without him, so he's in a foster institution. He searches for his father, wanting him and his bike. Through the intersession of Samantha, a hairdresser Cyril happens upon, he gets his bike back, and she offers to take him into her home on weekends. He remains aloof from her and gets involved with a young crook. Is Cyril intent on driving Samantha away - and what then?
