The Kiss(1965)

Original title: O Beijo

When a dying man receives a kiss from a bereaved man who tries to save him, the man is jailed as a homosexual. He is released from jail, but his life has been ruined by the incident -- and the man eventually is killed by his own father-in-law. The kiss that resulted in the eventual persecution and death of the man is never shown in this plodding, downbeat drama.
