S4·E6 The Way Station

With a storm brewing, Adam takes refuge at a way station, run by cantankerous Jesse and his young grandaughter Marty, who yearns to see what exists away from the way station. The station is also visited by Luke Martin, a killer who is running from a posse. He makes Marty an empty promise to take her with him and see the world together, but Adam steps in and suggests Luke let her alone. Everybody but Marty is relieved to see him go, but he quickly returns and holds everyone hostage to protect himself from the posse.
