Breaking into a local haunted 'hot-spot' is a common feature of many a horror movie.
But a group of teenagers in Costa Rica got more than they bargained for when they tried it for real.
A spooky video shows the teenagers exploring the Sanatorio Duran hospital in the South American country.
The hospital was used to treat sufferers of tuberculosis, also known as the white plague.
The teens can be seen looking round a seemingly abandoned room.
But when one of them flashes their torch against the wall, they see what looks like a figure scampering across.
The teen filming the video screams and runs at full pelt away from the scary apparition.
The hospital is known as one of the most haunted places in Costa Rica.
It was built in 1918 to treat thousands of patients, and also treated the mentally ill.
The little girl ghost is one of its most famous inhabitants, along with a group of nuns who are said to haunt the top floor.
