The most advanced chip, which can crack any code in a computer it's physically attached to, is stolen from the Home ministry. The only security video recording shows it was the work of a masked master climber who got away by motorbike. His trail leads to wheelchair-ridden George's mountaineering simulation club, so Rox goes undercover there. Prime suspect is champion Nicolas Klaus, who gets fired as instructor for recklessness, but he has an alibi for the actual use, during which missile launch codes are stolen.
