When a struggling publisher discovers his only successful author is blocked, he knows he has to unblock her or he's finished. With her newfound success, she's become too happy and she can't write when she's happy. The only trouble is, the worse he makes her feel, the more he realizes he's in love with her.
Unfortunately the movie Not Another Happy Ending is not yet available on HBO Max.
