Depressed by the direction his life is taking, Harry decides to take his own life by jumping off the Manhattan Bridge. At the last minute he's stopped by old friend Milt Manville, a successful stock broker. Milt, however, is facing his own problem: he has fallen out of love with his argumentative wife, Ellen. In a misguided effort to solve both of their problems, he introduces Ellen to Harry, hoping the two will fall in love.
