The Innocent (1985)

This densely-packed film is based on a book by Tom Hart about the struggles of a young Yorkshire boy trying to come to grips with squabbling parents, a doctor who wants to institutionalize him because of his epilepsy, and a mother who refuses to accept that he is different in any way -- and that is only the half of it. The boy, Tim (Andrew Hawley), also acts as a go-between for his friend Carns (Liam Neeson) who is having an affair with a married woman (Miranda Richardson). Eventually, things start to sort themselves out, and Tim sees life getting more interesting when he and his friend Win (Kate Foster) slowly get a relationship going.
