An experimental Willwear is luring the police out into ambushes.  Unit 8 tracks down the user, who has a grudge against the police over an old corruption case.  But when they capture him, it turns out to be a different person entirely!  The mystery goes deeper than they suspect when they find out a former researcher at the Defense Univeristy is involved...
