An alien thief has escaped to Earth with an object of critical importance to his planet. With the authorities close behind, the thief plans to hide by blending in among the people. However, his native form would make him stand out, so he’ll need to borrow a human body. And he has a specific one in mind. Catherine and Marcus are a young couple enjoying the evening of their engagement downtown when Marcus suddenly vanishes in a burst of shimmering lights. Unable to explain his disappearance, a mysterious man soon approaches Catherine, who tells her the thief he is chasing has taken over Marcus’ body. Unsure whether to believe him, Catherine reluctantly agrees to help when she learns the man can return Marcus to his body. But, as they begin to close in on the thief, Catherine uncovers a shocking truth about Marcus and the alien planet more fantastic than she ever imagined.
