52 stories of terror…

StarkTec Industries.

A towering 52-story skyscraper part of the Seattle skyline.

When Bobby and Brandon Stark stop by StarkTec to pick up their father for a baseball game, they suddenly find themselves walking into one of the most dangerous situations of their lives.

An uneasy feeling settles over them when they discover the security office deserted and every guard mysteriously missing. Determined to find answers, the brothers make their way toward their father's office on the top floor.

Suddenly, the building is plunged into darkness. Heavy security doors seal shut as StarkTec enters full lockdown. Moments later, the unmistakable crack of automatic gunfire echoes through the empty corridors, turning suspicion into terror.

The Stark brothers soon uncover a deadly hostage situation. Their father and several top executives are being held prisoner by a ruthless and heavily armed group with unknown motives.

Outnumbered, outgunned, and trapped, Bobby and Brandon must stay cloaked in darkness, fighting the unknown to survive the deadly threat at StarkTec and everyone's lives...

The phenomenon deepens...
