When Marty DePolo dies after eating a six-month-old hamburger, he is chosen to be the guardian angel of his best friend Steve Beauchamp.

Knowing that Steve lacks having an talent for a tealent show, Marty provides him with a singing voice which makes him popular with one girl in particular. Meanwhile, Marty helps an elderly woman through a transitional phase after she sees him at one of the singing shows.

Marty is re-assigned to rock star Sammy Noah after he does such a wonderful job by enlisting historical figures to help Steve.

Love is everywhere when Marty mis-fires Cupid's arrows. Steve mum, Aunt Pam and sister Katie are all madly in love with Mr Nitzke, making the school Halloween dance a once in a time time experience.

Marty discovers that he can travel through time. He goes back six months to when he ate the old hamburger. But if he didn't eat the hamburger, then he's not an angel, which means he couldn't go back in time, and Steve might actually eat the hamburger, which means . . . what?
