In 1879, the Cult of Death performed a dark ritual, trapping a man's shadow soul in an antique mirror. Over a century later, in 1990, the cursed mirror ends up in an antique store owned by Emma Thompson.

In the present day, Emma's grandson, Alex, a teenager with a mysterious birthmark, discovers the eerie mirror with his friends, Jake and Sarah. Curious, they perform a ritual they found online, unknowingly releasing the vengeful Shadow Man.

The Shadow Man targets descendants of the original cult members, gaining power by collecting the souls of firstborn sons with the birthmark. Alex, being a firstborn, becomes a primary target. As supernatural events escalate, Emma reveals the mirror's dark history.

Desperate for help, Alex and his friends team up with psychic detectives Marcus Reed and Lisa Carter. They uncover the cult's secrets and learn protective rituals, but the Shadow Man grows stronger. The group discovers an ancient artifact that might trap him, leading to a final, risky confrontation.

In a climactic battle, the group uses 13 mirrors marked with birthmarks to summon and trap the Shadow Man, ending his reign of terror. They reflect on their journey and find hope as they move forward, free from the curse.

"The Shadow Man Curse" is a tale of supernatural horror, family legacy, and the power of courage and sacrifice.
