In this artsy drama, a nihilistic youth from a wealthy family involves himself with an assortment of troubled souls until his father (who may be behind the son's troubles--psychoanalytically speaking) dies. When the young man goes to the wake, he soon chases all of his hypocritical relatives away by ritualistically dropping food from the buffet to exorcism them.
