After overhearing a fetish photographer at a bar making an appointment with a beautiful model, a mysterious sexual predator follows him home. Now, the artist is the prisoner of the sick home intruder, and as if that weren't enough, the invader uses the photographer's smartphone to text other models and set up exclusive photo shoots, posing as his assistant wearing a black mask. Much to the sadist's pleasure, the girls will be alone on the set, and above all, they usually give their consent to be tied up. What is the demented brute planning to do?
