Jamie is a crack addict whose struggles began when his family moved from a small rural community in Ontario to Calgary, Alberta. When he was 12, he fell in with the wrong crowd and started disappearing for days at a time.

He wanders the streets and parks of Oshawa, Ontario, a solitary figure in search of his next fix. Meanwhile, he has a four-year-old daughter he has never met.
