On Christmas Eve, 1947, siblings Harry and Phil sit watching between the stair bannisters as Santa comes down the chimney. All jolly, Santa tucks into the cookies and milk and lays out the boys' presents before giving Harry and Phil, alongside their mother, a knowing wink. Later that night, Harry creeps downstairs, only to discover Santa and his mother in a very compromising position.
'Christmas Evil', also known as 'You Better Watch Out' or 'Terror in Toyland', sees an adult Harry (Brandon Maggart) now thirty-three years on from that scarring night, where he works in a toy factory. Although he is often bullied and belittled by his co-workers, seemingly living a completely solitary existence, he has never lost that Christmas spirit. Far from it, as Harry is on a mission to become the next Santa, one that strives for purity, with the goal of eradicating those on his own maniacal 'naughty list'.
