The Happy Ending(1969)

When Fred asked for Mary's hand in marriage, she thought she had the happy ending she only read about in fairy tales. Now it's 16 years later; Fred has had an affair, and Mary drowns her sorrows in pills and booze, a dangerous combination that nearly resulted in her death the year before. As Mary rushes off to the Bahamas for a relaxing escape from her crumbling marriage, she reflects on the past and wonders just where it all went wrong.
