Gas is poured. A match is lit. Another church crumbles to the ground in a heap of ashes and embers. With plans to retire in the near future, Fire Marshal Rich Goeller is drawn into one final case that will define his legacy as an arson investigator. When three churches burn to the ground, each with similar patterns left by an arsonist, Goeller enlists the help of a local police detective, who happens to be his nephew. Using their combined experience, the two are closing in on the arsonist when a tragic event threatens to destroy their investigation and shake their city to its foundation.
