Outside In (1972)

This early Vietnam drama is about a draft dodger opposed to the Vietnam War and residing in Canada who returns to the U.S. to attend his father’s funeral.

He decides to remain and soon after he becomes entangled in the personal lives of two of his friends.  One of his pals is a Vietnam veteran whose pro-American sympathies clash with the anti-war sentiments of the draft dodger. 

The other buddy and fellow draft dodger who has served his prison sentence, takes his own life when he discovers that he is still classified 1A.
