Canvas (2007)

John Marino is a Florida construction worker struggling to make ends meet, while bringing up his son, Chris, and dealing with the increasing irrationality of Mary, his schizophrenic wife. For Chris, his mother's erratic behavior begins to have negative consequences at school. And, after Mary's hospitalization, a lonely John begins to build a sailboat that recalls a happier time in his life. Underlying the relationship between father and son is the belief that Mary will be better and the fear that she never will.
