Bubba Ho-Tep

Sebastian and Jack are residents of the Shady Rest Nursing Home in Mud Creek, East Texas. They truly believe that they are Elvis Presley and John F. Kennedy respectively, with Sebastian's story - Sebastian, an Elvis impersonator, who secretly traded places with the real Elvis in Elvis getting tired of his life - only marginally more credible than Jack's for one obvious reason, with Sebastian considering Jack to be "certifiable" in the process. Further, Jack is a conspiracy theorist who believes that his current predicament is all the doing of Lyndon B. Johnson who is still after him to eliminate him for good. Both in the twilight of their lives, they face a multitude of health problems - including mobility issues - one with which Sebastian is dealing affecting a sensitive appendage. In separate situations, they have heard scuttling sounds around the nursing home late at night, Sebastian who comes face-to-face with what he initially believes is solely a mean, fist-sized cockroach. Jack, however, has done research believing the cockroach to be an escaped Egyptian mummy who is coming to life by stealing the souls of the elderly in the nursing home, Bubba Ho-tep - what Sebastian names it - doing so by entering human bodies through one specific lower back side orifice. If true, the existence of Bubba Ho-tep would explain the rash of recent deaths at the home. As such, Sebastian and Jack join forces to find out as much as they can about the creature to come up with a plan to destroy it for good, their hope not only to save mankind as they examine their own mortality regardless, but also release the souls of their fallen "comrades".
