A dysfunctional family holiday, a possible murder, and a partridge in a pear tree. The Jaggers were once a tight-knit family. But after their mother’s tragic death years ago, the four children and their father have drifted further apart. The children grew up, moved away, and now have lives of their own. And Dad? Well, let’s just say his new live-in friend January also has a permanent residence in the uncanny valley. After a disturbing, violent Christmas two years ago the Jaggers wish they could forget, they’re reuniting in their childhood southern California home dubbed “the Pink Castle” to give celebrating the holidays one more shot this year. But in the days before they gather, the children each get a sinister note that reads Your mother was murdered. Could this be the bizarre work of January? Or is one of the Jaggers hiding a horrible, guilty secret?
