In the middle of the night, 112 dispatcher Boudewijn receives a report from a terrified young woman, Julia. She panics and tells them that she has been pursued for some time by a stalker, who is now at the door with a crowbar and trying to force his way in. Boudewijn immediately sends police to the scene, but when the intruder manages to break in via a broken window, Boudewijn has to throw everything into the fight to keep Julia out of the hands of her stalker.
