John McClane, the former mischievous and haunted police officer, is no longer the untidy and successful man we know. The past years have not been very nice to him. He is no longer working in the police department due to problems such as his upside down private life, divorce from his wife, and giving himself to alcohol.
Far from the movement and success of the old, he works in a government-owned security company where he tracks hackers. But danger and adventure will come and find him again when he least expected it.
