John Diabo was a cherished member of a tight-knit family in the Mohawk community of Kahnawake, near Montreal, Quebec. Nevertheless, John had been tortured by drug addiction for more than a decade. In 1998, he ended his own life at the age of thirty-one.

For John is the intimate story of John's battle with drugs and his eventual suicide. The film, directed by Dale Montour, John's aunt, is also a portrait of his family. Four years after his death, they break their silence. Courageously they share their stories of survival in the aftermath of unimaginable loss.

In moving testimony and family photographs, For John portrays the stark contrast between John's powerful life force and the force of his addiction.
