But there is more to Manglehorn than meets the eye: he’s an ex-con who, 40 years ago, gave up the woman of his dreams for a big ‘job’. He now obsesses daily over the choices he made. After a dramatic effort to start over, Manglehorn faces a terrifying moment and is unmasked as a guy with a very, very dark past.

After India’s father dies, her Uncle Charlie, who she never knew existed, comes to live with her and her unstable mother. She comes to suspect this mysterious, charming man has ulterior motives and becomes increasingly infatuated with him.
