Rachel Hamar—a Manhattan bank teller—lives nothing close to a Manhattan lifestyle. Residing in Washington Heights, NY, the only thing keeping her in The Big Apple is her mother—a long-time patient in a local psychiatric hospital. It’s December 2014, and the twentieth anniversary of her high school sweetheart’s tragic death. She’s not sure how much more heartache she can endure, especially after being told earlier in the day she no longer has a job at the bank. A casualty of downsizing.
In the midst of spiraling depression, Rachel receives a mysterious letter in the mail. When she opens it, she becomes cautious and skeptical of its contents and discards it as a mistake, concluding it’s simply addressed incorrectly or a postal worker’s faux pas in the midst of a busy Christmas season. But another letter arrives the next day. And another the day after that. Before long, she is in possession of several letters. Each one more puzzling than the last.
Thinking that someone may be playing a cruel game, she contacts the police, and this propels Rachel and the two detectives into one of the most bizarre cases they’ve ever encountered. Is it a friend’s cruel joke? Is it some stalker’s perverse idea of manipulation? Or is it something more?
