A Brazilian shaman sends former James Rance, a chrononaut presumed killed and missing in action years ago, on vision quest back from Amazonas to Arizona. He arrives at Dr. Isaac Mentnor's birthday party for his granddaughter Rebecca (9) and poisons her to blackmail him into sending them on a suicide mission through the sabotaged time-travel device.

After a classical ET-lookalike's baby-version (called Extraterrestrial Biological Entity, EBE) is hit by a prison transport which, in turn, crashes near Rosswell and a nearby poisonous bio-hazard. Frank is sent there on a mission so secret Isaac can't even brief him in advance. Frank has to find out on the job.
