A large family gathers in the country side for their very elderly grannies' birthday. One gift happens to be from their ostracized, black sheep nephew, and upon opening it, the two loveable grannies turn into rabid, flesh-eating monsters.
Unfortunately the movie Rabid Grannies is not yet available on HBO Max.
