An infant abandoned at a junction of four roads is adopted by a priest who finds it. The child grows up to be a soldier and participates in the Second World War. Most soldiers returned from the war carrying syphilis but this soldier did not get the disease. During peacetime, his courage earns him a means of livelihood. His curiosity about sex and another's treachery leads him to his first homosexual intercourse, in a state of intoxication. He gets the diseases gonorrhoea and syphilis and becomes a homeless wanderer. The insanity of the world infects him; the meaninglessness of his life and the pain of disease compel him to commit suicide. He does not succeed in his attempt at suicide. Overcome by a desire to confess, he walks into the house of a writer he respects and retells to him the story of his life.
