A recovering alcoholic is disturbed to find a young boy who shows up at his office claiming to be his son Jerry. The man is further angered when the boy shows up at his house. While the other family members carry on as if Jerry is a regular member of the family, the man insists that he has never seen the boy before in his life. The man's wife assumes that he has begun drinking again and is harboring delusions brought on by his inebriated state. The family, disgusted by the father's unwillingness to acknowledge Jerry as his son, ultimately leaves him. Driven back to drinking by the ordeal, the previously sober father ends up in a state of emotional ruin. In the final scene, Jerry visits another man, claiming to be HIS son, as the nightmarish pattern continues.
