Save the planet, or save yourself? When you can become anyone you want, the answer isn't as clear as you might expect...

On a cold night in an abandoned construction site, a dying alien grants five brave children the power to morph into any animal or person they can touch so that they can fight back against a secret invasion of evil, mind-controlling slugs called the "Yucks." Arnold knows this because he was there, hiding behind a half-built wall, and saw everything. He even accidentally got the same powers the children did!

But when Arnold realizes it's not a joke, and that he really can transform into any being he touches, he decides he wants no part of a terrifying battle against alien invaders. Instead he grabs the form of a hot stripper and sets off to make a new life for himself in Las Vegas as a body-morphing con artist who uses the bodies of sexy young women to steal from every casino in town.

His plan works perfectly right up until the night when he stays morphed for a little too long and accidentally gets stuck in one of his gorgeous, borrowed bodies. Now, robbed of his powers and with no choice but to learn to live his life as "Annie," he doesn't know where to turn for help. Even worse, the horrible alien Yucks may have finally caught up with him...
