Sawyer is a special agent from the FBI involved in a mission that takes a very serious turn and after that loses one foot, but also a few colleagues. Ten years later, still suffering from that incident, both physically and emotionally, Sawyer handles the organization of security systems for the tallest buildings in the world, being a renowned consultant on the subject. He is hired by a Chinese real estate developer to protect the Pearl, considered to be the highest and highest superstructure in the world, three times higher than the Empire State Building in America. But shortly it turns out that safety is not even the strength of the building, and Sawyer slammed in the middle of a murder plot.
