Dead Man's Hill (S03E07)

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, who died in 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.
