S03:E07 - Dead Man's Hill

Marguerite and Roxton discover a strange corner of the jungle, where a hangman's noose dangles from a tree and a tombstone marks the grave of one J. Roxton, died 1875. Suddenly, Roxton himself is transported to the wild west, where Challenger is a cruel lawman, Marguerite is a lone frontier woman, Malone is a gunslinging bounty hunter, and Veronica is a trade post owner with a shotgun. While Roxton tries to avoid Challenger's bullets, he must wake his friends up to the real identities in order to escape this bizarre parallel reality.
