When bodies start washing up on the shore in Salem Harbor, Massachusetts, an elite task force of FBI agents, profilers, and detectives join forces in a remote log cabin to decode the clues and stop the killer from targeting another victim.

Agent Tala Marshall overcame a childhood of deep generational wounds to become the country's best criminal profiler. Now she faces her most challenging case yet, racing against the clock to profile the elusive killer before they strike again. She must partner with Wilder Mason, a local detective convinced that the murders are connected to the Salem Witch Trials of 1692, and Tala builds a connection to the task force that helps her come to terms with her tumultuous past. But Wilder wants more and is determined to find the key to both the case and Tala's guarded heart.

Can they find the undercurrent that connects Salem's past and present before another victim washes to shore?
