Turn the River (2007)

In New York City, Gulley, who's in middle school, lives with his father and step-mother; his paternal grandmother dominates the family's life. In secret, he's recently been in touch with his mother, Kailey, a pool hustler, who wants to win big and take Gulley to Canada. With the help of Teddy Quinette, who runs Quinn's Pool Hall, Kailey may get her shot at big money. Can she win the match, keep her son's confidence, and, using fake documents she gets from Markus, a friend of hers, make it to Canada to start a new life?
