UFO enthusiast Tom is excited about his astronomy club's overnight field-trip for two reasons. The first reason is that they'll be hiking near a UFO hot spot, where strange sightings and paranormal experiences are bizarrely common. The second reason is that his crush, the hottest girl in school, Lucy Ames is coming along and through some mix-up or twist of fate they're sharing a cabin!

After hitting it off Lucy and Tom sneak off together, but what they find in the desert shocks both of them. An encounter with an extraterrestrial being and an ominous craft causes them to switch bodies! If they want to switch back it's going to take a lot of experimentation and exploration but luckily they're both up to the challenge.
