An American TV series based on (and following up) the movie "Osmosis Jones". It takes place inside the body of teenager Hector Cruz (referred to by the characters as "the City of Hector"). A year after Ozzy and Drix defeated Thrax and saved Frank from dying in Osmosis Jones, Ozzy and Drix chase a scarlet fever bacterium (possibly thanks to Frank resuming his poor eating habits). During the chase, Ozzy, Drix and the germ get sucked up from Frank by a mosquito and arrive on a teenager named Hector Cruz. After some initial problems with their new home, both are installed as Private Investigators, vowing to protect the wellbeing of Hector from any viral threat.
