Harold (Stan Rowe) is an old age pensioner, suffering from O.R.D. or the onset of rigor disease. He can't get out and about as much and gets forgetful. Then there's the stiffness. He can't even touch his nose. What is the ultimate effects of O.R.D.? Well, it turns you... into a zombie. And it's affecting more and more UK males. Enter Penny, (Sarah Spencer) a cheerful, dedicated but lonely nurse, as his care helper. She'll engage in therapy with him, to delay the disease's effects. However, during the onset of the disease's later stages, loss of mental faculties and violent behaviour is inevitable. Already there have been reports of attacks, which prompts a trio of baseball bat wielding vigilantes to patrol the area, taking down any errant zombie they happen to find. Meanwhile, Harold is still getting by, and starting a tentative friendship with Penny. Will a cure be found? Or will Harold have to be taken out like so many before him?
