Without warning, Detective Andy Blake's personal life seems to be spinning out of control. She already has enough on her plate dealing with the opioid crisis that has crippled her hometown of Sault Ste. Marie. Adding to that are her efforts to balance it all with an admitted infatuation with the charming Dr. Campbell who is on special assignment advising the health responders dealing with a new threat: a pure form of the drug fentanyl that has added to the crisis.

Meanwhile, a young boy with special needs and a young couple become integral to the intriguing outcome of Andy's investigation.
