David Hume and his new partner Ian Farve must track down a gang of androids with abnormally high intelligence gained from experimental use of memory implant technology from the big corporation Rekall.

The Detectives hunt for the androids take them to Mars.

When investigating the murder of the head of the Nexus dating service, Farve finds a list of people implanted by a Rekall mind-control project, and much to Hume's horror Olivia is on it. Adding to his trouble is his father, who once again has trouble with his retirement home.
