KAOS agent Dietrich has decided to defect and become an informant. Although this is good news, the Chief is still concerned, seeing that no KAOS defector has ever lived long enough to testify. With the Smarts' nanny unavailable, the Chief's plan is to have Dietrich disguised as the nanny and staying with Max. The local KAOS branch hires the Exterminator (William Schallert), a top assassin (and accountant) for hire, who uses his arsenal of booby traps, arrows, and bombs to try to kill Dietrich.
