Actor Joe Cummings from Manhattan, New York, confronted his girlfriend when he noticed food he wasn't eating kept going missing.
But after his partner denied it, the bemused bloke set up a hidden camera in his kitchen to find out the truth.
And it was utterly creepy.
Night-vision footage shows a woman drop down from a hard-to-reach cupboard above a door.
She carefully places her feet on a nearby table before quietly stepping onto a stool and then down to the floor.
