Trying to hitch a ride on a desolate California road, fresh-out-of-prison Max (Gene Hackman) meets ex-sailor Lion (Al Pacino). They are both headed east, as Max dreams of opening a deluxe car wash in Pittsburgh and Lion believes that the wife and child he left behind will still welcome him home. The two decide to journey together, forging an increasingly deep yet uncertain friendship, as Lion teaches Max how not to be so pugnacious and Max senses Lion's fragility. When the pair hits Detroit, Lion finally gets in touch with his wife and discovers how she really feels. When Lion is shattered by the revelation, Max must decide if he should forge on alone or sacrifice his carefully guarded savings to help his friend.
