The two pay a visit to Chill, a flu vaccine and one of Ozzy's informants, who directs them to Thrax's hideout in a germ-ridden nightclub in a large zit on Frank's forehead. Ozzy goes undercover and infiltrates Thrax's gang, where he learns that Thrax, wanting to be known as the most dangerous virus in medical history, intends to masquerade as a common cold while, using his knowledge of DNA, killing Frank in a record forty-eight hours. When Ozzy is discovered, Drix comes to his aid, resulting in a massive brawl that culminates in Ozzy destroying the zit using a grenade from Drix. Its destruction causes it to land on Mrs. Boyd's lip during a meeting with her and Frank, ruining any chance for him to apologize. In response, Phlegmming closes the investigation, has Ozzy fired from the force, and orders Drix to leave after reminding him that his services are only temporary.
