Kate Tessler and her crew of misfits set out to blow the whistle on two feuding crime families . . . Former war correspondent Kate Tessler has solved multiple murders since returning to her Arizona hometown, to the grudging appreciation of the local police. Now Detective Padilla and the FBI approach Kate with a proposal. Two Russian crime families have rented a private historic train to the Grand Canyon for their children’s wedding. The route is scenic and remote. No cell phones. The FBI needs to surveil, but anyone infiltrating the train must be above suspicion. Kate poses as herself, sent by the newspaper to cover the society wedding, while her sister Jen is the photographer. Their multi-generational and eccentric crew pose as train staff. The goal is to observe, but that quickly derails when the groom disappears, and a search for him turns up a dead body. Everyone’s a suspect and trapped on the train. The mob families won’t contact the police, so it’s up to Kate and friends to uncover the truth before their whole mission goes off the tracks.
