With Eddie's help, Cade poses as a math genius to investigate the mysterious death of a grad student in Boston who apparently died of the bends on dry land. He takes the student's place in a think tank aiding the government with a communications satellite. He meets Lara, who was the last to see the victim alive, and discovers she is telekinetic when she attacks him psychically. Cade is then captured by the mysterious Colonel Grace (Dana Brooks), a government agent who has been hunting him since the murder of his wife. She agrees to expunge Cade's record if he captures Lara for her, as the government wishes to use her for covert operations. Cade and Eddie discover that the communications satellite is actually armed with nuclear weapons -- but is it to defend or attack the Earth?
