Blake, a somewhat eccentric yet effective hitman, decides to become more famous by killing the world's greatest hitman, Gunther. For that he hires a documentary crew to have video proof that he did it and document the process. He also puts together what he describes as an "unstoppable team" composed of his friend Donnie, a former miner skilled with the use of explosives, Sanaa, the daughter of a legendary hitman Rahmat Fairouza, nicknamed "the nightmare", who is overenthusiastic in his support for his daughter's career, Gabe, an unexperienced technology 'expert', and Ashley, Blake's elderly and sickly mentor. As Ashley explains to the documentary crew that he is in it because Gunther betrayed him, he has a heart attack and the team is left incomplete.
