Artie Barnes is a nerd who doesn't believe in magic.

He lives by astronomer Carl Sagan's creed: extraordinary claims require extraordinary proof.

Then Fred shows up.

He's a teeny-tiny man with teeny-tinier wings. He claims to be the Tooth Fairy — and he's got an ultimatum:

Believe in him… or they're both gonna get PEWED.

Snuffed out by the Paranormal Entity Workforce, Enforcement Division.

When hit-fairies come nursing a grudge, Artie must fight to save himself — and a Tooth Fairy he doesn't want to believe in.
