As ominous chaos envelops the Casa de la Loco Sanitarium, a nefarious figure emerges, overpowering a nurse and assuming her identity. This Thief blends into the guise of a medical professional, kickstarting a crime spree that ravages all in its path. Not only does he steal a firearm and commandeer a vehicle, but he also amasses a small fortune in stolen cash while ruthlessly eliminating an unlucky loan office manager.

As he bolts from the scene of his heinous act, the Thief inadvertently discovers a macabre yet fascinating cemetery where somber burial rites are unfolding amidst the eerie strains of bagpipe music. A curious group of mourners, including an undertaker and a caretaker, gathers to pay their respects, drawn together by a strange blend of respect and curiosity. Just as the service wraps up, desperation mingles with greed, prompting the Thief to peer into the open coffin, mistakenly believing it to be a hiding place from his growing troubles.

His fateful choice leads to disastrous consequences as he accidentally strikes a tuning fork buried alongside the skeletal remains, setting off an unsettling resonance that sends him into violent spasms. The coffin lid shuts with a finality that seals away his ill-gotten gains, and the Thief tumbles into a freshly dug grave, knocking himself out in the process.

Upon regaining consciousness, he embarks on a dangerous mission to hunt down everyone involved in the bizarre funeral rituals, driven by an unquenchable thirst for vengeance. In his relentless pursuit, he spares no one who dares to obstruct his path, creating a horrific trail of carnage and despair that leaves a chilling mark on all he encounters.
