Jesus' Son (1999) on Netflix

A gentle and usually mellow young man, who sometimes knows things before they happen and gets vibes of premonition, tell us his story: how he met Michelle in Iowa in 1971, how he got the name Fuckhead, how she introduced him to heroin and their falling in love, his thieving, his hospital work and their time in Chicago when she gets pregnant, detox, going to Phoenix to live, AA meetings and a dance, working at a care center where he learns to touch the residents, and modifying his daily schedule so that he passes a neighboring Mennonite household at the right time to hear the wife sing Gospel songs in the shower. Slowly, very slowly, FH lets his gifts emerge.
