Based on the Dark Horse comics, Resident Alien follows a crash-landed alien named Harry whose secret mission is to kill all humans. In season three, Harry is vowing to work with General McCallister to rid the Earth of the Grey aliens – a task made more difficult when he discovers that the Grey Hybrid Joseph has taken a job in town as the new Deputy. Joseph isn’t Harry’s only obstacle – Harry struggles to balance business and his personal life when he falls in love for the first time.

Meanwhile, Asta and D’arcy move in together and struggle to discover their purpose in the world, Sheriff Mike and Deputy Liv continue their quest to find out who killed the Alien Tracker, and Ben and Kate are forced to deal with the subconscious repercussions of their alien abductions.
