Will is a rich, child-free and irresponsible Londoner in his
thirties who, in his search for available women, invents an
imaginary son and starts attending single parent meetings. As a
result of one of his liaisons he meets Marcus, a strange
12-year-old boy with problems at school. Gradually, Will and Marcus
become friends and, as Will teaches Marcus how to be a cool kid,
Marcus helps Will to finally grow up.
