When a young woman goes missing, Detective Alyssa Wyatt is called to the scene. Will she and her team be able to solve the crime and locate the woman in time? It's their usual Thursday girls' night in, and best friends Skye, Elena, and London are hanging out at Skye's house in New Mexico: eating junk food, drinking wine, and playing with Skye's children, Carter and Abigail...until the intruders arrive. Hearing horrific screams from Elena and Skye, London hides the children, tiptoes out to see what has happened, and then disappears. After Carter raises the alarm, Detective Alyssa Wyatt is called in to investigate a crime that appears to have no motive, no evidence, and worse still--no sign of London. As Alyssa and her team dig deeper, the truth is always just out of their reach, but what is clear is that they need to find London...and fast. As they uncover a link between the murders and a sinister local cult, can Alyssa find the young woman who has vanished without a trace before London joins the list of victims?
