Hal is a party animal.  Out every night, picking up cute girls.  Hanging on to a girl for only a short while until he finds something wrong with her, or until she gives up on him.

He runs into a hypnotist who changes his outlook.  He sees people who they are on the inside.  The beautiful girl inside the shell.  And in Hal's case, he completely falls for the most beautiful girl he's ever seen, inside a very, very large woman.

And predictably in the end, he learns that beauty is also inside, not just skin deep.  For an hour and forty-five minutes the movie goes traipsing down a predictable path.  But there was a very touching moment when he sees the little girl in the hospital that was just the cutest button earlier, now with true eyes is a massively scarred burn victim.  He holds her and understands.
