Tim is a young man with below average intelligence. He works as a builder's labourer and is often taken advantage of by his fellow workers and other people. Mary asks Tim to work around her yard for a day. The day stretches into a few weekends and the two soon become good friends. Some people however are suspicious of their friendship which seems to be continually strengthening accusing Mary of taking advantage of Tim's innocence. Will changing circumstances in Tim's family life change his relationship with Mary?
