Plot Synopsis

Inspired by the Swedish novel (2004) and movie (2008) of the same name, LET THE RIGHT ONE IN is a 10-part drama series that centers on Mark Kane and his daughter Eleanor, whose lives were changed 10 years earlier when she was turned into a vampire. Locked in at age 12, perhaps forever, Eleanor lives a closed-in life, able to go out only at night, while her father does his best to provide her with the human blood she needs to stay alive. Forever on the run, forever on the hunt, they have returned home at last to New York City in a desperate bid to find a cure. Others are drawn into their nightmare -- a close friend from the past with everything to lose, a homicide detective raising her son alone, and an heiress to a pharmaceutical empire trying to save her infected brother. LET THE RIGHT ONE IN premieres on Showtime on Sunday, October 9, 2022 at 10pm ET/PT, with an early debut on non-linear platforms on Friday, October 7.
