An alleged arsonist. A deadly cover-up. Can this K-9 sniff out the truth?

Evidence at a fiery car crash leads K-9 Officer Nelson Rivers and his accelerant detection dog Diesel to Mia Turner — a woman previously accused of arson. But when a gunman targets Mia during their first meeting, Nelson suspects she might actually be innocent. Only Mia’s hiding something, and Nelson’s been burned before. Can they trust each other to catch a killer…before the threat engulfs them both?
