Years after he fought his way out of an inescapable prison, Ray Breslin has organized a new top-notch security force. But when one of his team members goes missing, Breslin must return to the hell he once escaped from to save his friend from the prison's brutal human battleground known as Hades.
Leading a next-gen security company of highly trained operatives, the masterful escape artist, Ray Breslin, continues to push the boundaries of what is humanly possible, after his narrow escape from death in Escape Plan (2013). However, after a failed operation, Ray's protégé, Shu, will find himself trapped in the world's most sophisticated prison: the impregnable and ever-shifting, Hades. Now, to rescue Shu, Breslin infiltrates the futuristic facility which is supervised by a state-of-the-art artificial intelligence; nevertheless, has anyone ever escaped from Tartarus' dark realm?—Nick Riganas
Sometime after escaping The Tomb in the first film, Ray Breslin (Sylvester Stallone) starts up a security company with Hush (Curtis "50 Cent" Jackson) and Abigail (Jaime King) serving as his senior staff members, recruiting Shu Ren (Huang Xiaoming), Jasper Kimbral (Wes Chatham), and Luke (Jesse Metcalfe) as field operatives. During a hostage rescue mission in Chechnya, Kimbral breaks unity with the team by relying on a computer algorithm to complete the mission, causing a complication that results in a female hostage dying from stray gunfire. Due to the botched outcome of the rescue mission, Kimbral is fired from the team.
One year later, Shu is requested by his family cousin to protect satellite businessman cousin Yusheng (Chen Tang) from technology giant Ruscho. Ruscho made three attempts to buy out Yusheng's technology, only to be rebuffed. At Yusheng's party in Bangkok Thailand, masked men try to kidnap Yusheng. Shu beats them with his fighting skills, but they shoot him with electric guns knocking him unconscious.
When he wakes up, he finds himself in prison where he is asked to battle with another prison inmate Akala (Tyron Woodley). He wins the battle, and his reward is that he gets two hours of time in sanctuary. Meanwhile, Luke, Hush, and Breslin try to find Shu in the outside world after noting his disappearance along with his Yusheng. After the sanctuary time, when returning to his cell, Shu sees Kimbral inside the prison. Recalling all of the knowledge learned from Breslin, Shu makes plans to break out of the prison. Later Shu meets Gregor Faust (Titus Welliver), nicknamed "The Zookeeper" who calls this prison The Zoo.
The zookeeper informs Shu that his cousin has given up his first patent technology and all its specs and details, now they want his second patent, which Yusheng does not want to give to them. The zookeeper asks Shu to help retrieve this second patent. When Shu asks his cousin about these patents, Yusheng reveals that his first patent is nothing, but his second patent is very dangerous if it gets into the wrong hands, as anyone can control any system through his second patented technology, any defense systems can be shut down, any nuclear weapons can be launched.
Shu meets up with Kimbral and he informs them that they are in H.A.D.E.S. (High Asset Detention Service) Prison, built using technology, Galileo, and that he has been in the prison for couple of months now. While on the outside, Breslin finds that Shu and Yusheng are in HADES and learn that it is also funded by a mysterious group responsible for The Tomb. Breslin takes help from acquaintance Trent DeRosa (Dave Bautista), while Luke gets caught and is placed in HADES prison.
Shu works on getting the layout of the prison but runs into complications. After getting information from the cook, Shu learns that the prison shifts every night and all his hope of getting the layout of the prison shatters. Then Kimbral informs him that Legions (3 other inmates, computer geeks from Norway one of whom was involved in designing the prison) can help him if he find who is the head of the three people. As the head, Count Zero, has specs of the prison. Shu befriends them and questions Count Zero for the layout. The following day, Shu, Luke and Kimbral are in the control chamber tied to chairs and forced to watch through a monitor as Count Zero is taken by the prison guards. Here, Kimbral reveals that he is the one running the Zoo after being approached by the Tomb creators when Breslin dismissed him from the company. The entire prison population turns against Shu for betraying Count Zero.
Breslin and DeRosa deduce Kimbral's identity as the prison's owner and learn that Kimbral kidnapped the operatives as revenge. Breslin is also taken to the prison and Kimbral challenges him to break out of the Prison. Using a high-tech communications tooth implanted inside Breslin, Hush tries to get the layout of the prison from the outside. Breslin, Shu, and Luke communicate without cameras noticing them when Hush momentarily disables the cameras. Yusheng, Akala, the remaining two Legions, and the cook help on the prison escape. Hush gets 100% layout of the prison and shuts down Galileo. Everyone uses the chance to get to the medical center. The Legions and Akala stay there, while Breslin, Shu, Luke and Yusheng continue on with their plan. While attempting to maintain control of the medical center, the Legions and Akala are killed by Kimbral's men. Breslin, Shu, Luke and Yusheng get scattered.
Shu and Faust get engaged in a knife fight, ending with Shu killing Faust, while Breslin gets to the control room and enters into a hand-to-hand fight with Kimbral. When Yusheng blows up the Solar panels, DeRosa uses the distraction to find the location of HADES and enters into the prison by force knocking down one of the walls. DeRosa saves Luke while killing the guards before destroying Galileo. Shu and Yusheng are able to exit HADES safely to meet with Hush waiting for them. Breslin wins the battle and meets with DeRosa and Luke in the control room. Later, Breslin reveals to Luke that HADES is located in Atlanta. As they work, a man contacts HADES calling for Kimbral. Breslin warns him that while he doesn't know who the man is, he will now be coming after him for his role in the events.
