Six psychiatric patients arrive at an isolated warehouse to complete Dr. Marlow’s treatment.

Upon arrival, all patients suffer a series of disturbing hallucinations.

Inspector Héctor Castro appears to take charge of the doctor’s murder case.

The next to be questioned is Ana Morantes, who recalls a vague memory.

As Castro continues his interrogations, a dark secret and a possible motive are revealed.

During Fariba’s interrogation, Castro dives deeper into a patient’s identity.

The revelation of The Horse at Norman’s ceremony is a threat to Dr. Marlow.
