I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Purgatory Movie plot: An outlaw band led by Blackjack Britton and Cavin Guthrie rob a bank. During the subsequent gunfight, a woman named Dolly Sloan is shot and dies in the arms of Cavin's nephew Sonny. The gang flees and is pursued by a posse. After passing through a dust storm, they enter a tunnel and emerge at the other end in the town of Refuge. The gang lie about their injuries and convince the townspeople to help them tend to their wounds. The gang is puzzled by the town's residents, who don't carry guns or drink at the saloon and who immediately flock to the church whenever the bell rings. Sonny thinks he has seen some of the town's residents before, but he is unable to remember where. He witnesses a mysterious stagecoach arriving at night with a woman in it who is identical to Dolly Sloan. The rest of the outlaw gang begin causing trouble in town, occupying the saloon and making plans to steal supplies before leaving. Sonny befriends a woman named Rose who tries to steer him away from asking questions about the town and the people in it. As he investigates further, Sonny realizes that the town appears to be occupied by former notorious outlaws. Sonny works out that the sheriff is actually Wild Bill Hickock, the bartender at the saloon is Jesse James, and the town doctor is Doc Holliday. He repeatedly confronts the outlaws about their true identities but they all deny who they are and advise him to let it go. Sonny talks to a man he believes is Lefty Slade, now a gardener named Lamb. He grabs the man's arm and sees a bullet wound on his wrist, prompting the man to admit he was Slade. Before Sonny can ask more questions, some of Blackjack's men tear up Lamb's garden. Enraged, Lamb grabs a shovel and beats one to death. Instantly regretting his action, Lamb begins to cry as a mysterious Native American man called The Gatekeeper appears at the edge of the woods. Lamb willingly leaves with The Gatekeeper while the townspeople gather to watch. Lamb is lead to a fiery pit that is implied to be Hell and is cast in, screaming in...
