The story takes place in the Thunderbolt team training center in Seattle, where Allen (Adrianne Palicki), Ward (Ty Olsson) and Hall (Sam Jaeger) are the backbone members. One day, the team received a tip-off that a drug deal was going on in an abandoned freight center, and the team immediately launched an operation, and indeed hit the transaction scene head on. After the fierce gun battle subsided, the team members found a tied man in the container. The man's name was Scorpion (Michael Jai White), and a chip was implanted in his arm, which recorded all the criminal evidence of the gang. Scorpion became the most important witness of the Thunderbolt team, and the gang certainly would not sit idly by. They sent various killers to launch a fierce attack on the training center.
