A man is saved from drowning off the coast of Cambodia, but a case of amnesia prevents him from knowing who he is or how he got there. While he can't remember his own name, he has knowledge equal to that of a super computer. He soon gets mixed up in solving mysteries, even though he can not figure out his own.
The series was re-cast between the pilot and the show's launch. The previous cast included rock singer Meat Loaf.
