A remake of the Swedish film Let the Right One In, this 2010 version is still set in the 1980's, although the location has changed from Stockholm to Los Alamos, New Mexico. There a 12-year-old boy named Owen (Kodi Smit-McPhee) lives in an apartment building. A girl named Abby (Chloe Moretz) moves into a unit with a man (Richard Jenkins) that Owen takes to be her father. Soon afterwards, a series of bizarre murders take place, prompting an investigation by a policeman (Elias Koteas).
