There are a couple (I think) that are drving along a deserted road and run out of fuel. They noticed a house a little back had it's lights on. So like the urban legends walk back to ask for help. They climb in a window and look around and I seem to remember that they see some spooky stuff. Not sure, anyway it ends with a scene where one of them is hiding in a room behind a door with a sword taken from a suit of armour, the camera view shows you what is round the door way and it turns out to be a room full of people waiting to give the guy/girl a surprise birthday party. Someone with a cake and candles goes to walk through the doorway to say surprise but at that moment the person hiding behind the door swings the sword round the doorway. Just before the sword decapitates the cake bringer the sword swinger sees the person holding the cake and the surprise party behind them. Nothing they can do though and person is decapitated. Now I also think this was part of a short stories type movie like tales of terror but can't be sure. Pleeeeease help, it's driving me up the wall!!!!
