It's the most moving movie ever. Two childhood friends (black and white) have come to the conclusion that their lives have not worked out and should be ended. White for a suicide attempt (repeated) was placed in a psychiatric hospital, and black still hides this intention, although he tried to commit suicide.
Then a black friend organizes the escape of a white man from the hospital, and before committing suicide (shooting each other on the count of three) they decided to first deal with those who were unpleasant to them in life.
That's the movie.
