Overview:The future looks bleak for today's youth - austerity, soaring house prices, student debt, a broken political system... And to add insult to injury, their hard-earned taxes are being eaten up by the elderly: smug, self-satisfied, small-minded, 'Little Englander' pensioners whose sole remaining purpose in life is to make it a misery for everyone else. In a small British town, tensions come to a head when a mysterious military convoy crashes outside the Sunnywise Retirement Home. The vehicles release a toxic substance, which leaks into the local environment and infects the residents of the retirement community. The symptoms of the infection quickly manifest: an overwhelming appetite for raw flesh. They're old, they're angry and they're on the rampage. As the military scrambles to control the outbreak and keep everything out of the media spotlight, a group of regular teenagers find themselves in the thick of the battle against these flesh-eating baby boomers.
