The only lead is a dilapidated RV that had been parked on their street. Heading the investigation, Detective Loki arrests its driver, but a lack of evidence forces the only suspect’s release. Knowing his child’s life is at stake, the frantic Dover decides he has no choice but to take matters into his own hands. The desperate father will do whatever it takes to find the girls, but in doing so, may lose himself, begging the question: When do you cross the line between seeking justice and becoming a vigilante?
