Ever wished you could be a fly on the wall? For Harry, that wish comes true - just not in the way he expected.
A dull college chemistry class turns chaotic when Harry and his best friend George start daring each other to drink bizarre chemical mixes. But George secretly adds a crushed fly to Harry's concoction. That night, Harry begins to change - and soon discovers he can transform into a real fly whenever he wants.
What starts as a weird party trick quickly attracts the attention of MI5, who see potential in his unique "talent." Suddenly, Harry's being sent on missions no other spy could survive, uncovering classified plots, and dodging danger at every turn.
But keeping his double life under wraps isn't easy - especially when, after every transformation it leaves him completely naked.
