Tracker — Season 1

An alien security officer comes to Earth to track fugitives from his planetary system who have taken over the bodies of Earthmen. Unfortunately, while they enter human bodies and thus have a knowledge of humanity, the alien bases his physique on a poster of an underwear model for the Cole brand. Thus the alien ("Cole") is pretty much clueless about humans and human physiology. A passing bar owner, Mel Porter, takes pity on him and takes him back to her hotel. Cole quickly cobbles together some Earth technology to track one of the escapees, Rhee, who killed his wife and child. He defeats Rhee thanks to his time-stop abilities and removes her essence from the human body she inhabits. He also meets Zin, a scientific genius and alien who masterminded the escape. At the end Mel takes on Cole full time at her bar while Cole prepares to track more of the escapees.
