By day, The Hollow Man is invisible—a ghost in the eyes of the world. He works as a night auditor in a nondescript hotel, his existence empty and mechanical, devoid of meaning, family, or excitement. Every night, as the world sleeps, he stares at the darkness of his unfulfilled life. The isolation and boredom eventually lead him down a dangerous path.

In his desperate quest to feel alive, he commits small, petty crimes at first, gradually escalating into terrifying acts that shock his community. For The Hollow Man, it's not about wealth or revenge; it’s about the rush—the only thing that breaks the monotony. He thrives on the fear and chaos he creates, his crimes growing bolder as his need for excitement intensifies.

Yet, his quiet, unassuming nature makes him the least likely suspect. How could this boring hotel worker be the mastermind behind such terror? But Detective Eva Grant, sharp and persistent, is not fooled by appearances. She suspects that the invisible man hiding in plain sight is the key to unraveling the crime spree that haunts her city. With each crime, the net tightens, and The Hollow Man must stay one step ahead, or risk being exposed as the ordinary man capable of extraordinary horrors.
