The Secret (1992)

Mostly because of a struggle with pride, Mike Dunmore has lived his whole life keeping a secret which he believed would only cause shame if it came to light. Personal relationships with his son Patrick have been strained as a result. The only ones who ever knew anything about it were his deceased wife and his best friend and co-worker Thurgood, who both agreed to help keep it covered up for him as long as they could. However, when his treasured grandson begins to experience the same problems, Mike realizes that he can't hide his secret any longer, or if he tried to, it would be most difficult--even more so when he is endorsed and volunteers to run as a candidate for local election.
