Jon Martello (Joseph Gordon-Levitt) is a handsome, good old-fashioned guy known as Don Jon for his ability to bed beautiful women at will. But ironically, even the finest fling doesn't compare to the bliss Jon finds alone-watching porn on his computer. Barbara Sugarman (Scarlett Johansson) is a gorgeous, good old-fashioned girl raised on romantic movies, and she's determined to find her Prince Charming. Wrestling with expectations of the opposite sex, Jon and Barbara struggle against false fantasies to find true intimacy in this unexpected comedy written and directed by Joseph Gordon-Levitt.
