RogerDog Rescue of Helena, Montana, is operated solely for the benefit of Montana dogs, no transported outsiders allowed. When a fellow rescuer dies while completing a transport for an infamous Butte operation, Betty Mills, Kelly Boyd and Cici Vargas don't believe it was an accident. They infilter the Butte group, just in time to partake in a rescue flight from Mexico. Plans go awry and they unwittingly wind up with something that multiple suspicious characters want to get their hands on. Is it the foreign dogs themselves or something else? The body count begins to grow and the danger spreads to other RogerDog workers. Can they solve the mystery before it is too late?
