Resident Alien (2021)

An alien, who has crash-landed on earth on a mission to destroy humanity, assumes the identity of Dr. Harry Vanderspeigel so he can remain undetected by the residents of Patience, CO as he searches the snow-covered Colorado mountains for pieces of his ship. He learns "to be human" by watching Law and Order and mimicking the late, great Jerry Orbach. One day the sheriff of Patience, Mike "Big Black" Thompson, and his deputy, Liv Baker, show up at his isolated cabin. There has been a murder in town and they need a doctor. The murder victim is the town doctor. Soon, he finds himself in the role of the new town doctor, putting him in constant contact with the townspeople. Something, until now, he has assiduously avoided. As he spends more time with humans, he learns more about them and what makes them human. This gives him pause but he is still determined to complete his mission to destroy the people of Earth. He learns one person in town can see him in his true form, complicating matters. —dragongyrrl
