Overview: Alexi Sebastian, a master impersonator, attempts to kill someone who was about to reveal the secret of the KAOS coding system. Alexi disguises himself as the Chief to confuse the situation even more. Max and 99 must guard Tanya Lupescu, who has memorized KAOS' codebook. An attempt to hide her in a hotel fails, so CONTROL decides to hide her in Max's apartment. KAOS hires master impersonator Alexi Sebastian to kill Lupesco. Sebastian has successfully disguised himself as Johnny Carson and Max's Aunt Rose, so CONTROL has him listed as a 101 - shoot on sight. Sebastian disguises himself as the Chief and gets inside the apartment, but the real Chief shows up and Max is confronted by two Chiefs. Can Maxie pick the correct Chief?
