When Morgan and Lewis receive a cryptic letter and a key from Mr. Lee, they get to enter his garage studio and see his life-like costume creations. Is the alien they meet there just another one of Mr. Lee's movie robots or is it a bonafide extraterrestrial? Morgan and Lewis must uncover the details to solve the mystery while they also try to convince their town that the Sasquatch footprint located in the woods is the real deal and not a fake made by Mr. Lee's Sasquatch robot. Yes – robots, aliens, and Sasquatches abound and the big question through it all for Morgan and Lewis is – what is real and what's pretending to be real. With so much at stake, they must be able to tell their friends from their foes.
