Steve's dad, Casey, has returned to the family but when Grandpa moves in as well, Steve has to learn a lesson in respect and Marty learns his invisibility isn't limitless.

Steve throws Marty a sixteenth birthday party even though he's dead and Marty insists on inviting kids from school and other dead people like Beethoven, Abraham Lincoln (you get the picture)...

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?

Marty helps Casey win a toy, but an athlete thinks that she has got talent and tries her out for a professional baseball team. Grandpa also gets reunited with his dead wife.

Marty calls himself Vlad and dresses up so he can impress the girl, Nia, that he liked before he died. He only hopes that the Head won't find out.
