Jay and Gal are two former British soldiers turned hitmen. While Gal is laid-back, Jay is still reeling from a disastrous mission in Kyiv. Despite his wife Shel's urgings, Jay has not obtained full employment, to the point where they are financially broke.
Shel organizes a dinner party, which was joined by Gal and his girlfriend Fiona, a human resources manager. During the party, Gal reveals he has a new job for them, which Jay eventually accepts. Meanwhile, Fiona goes to the toilet, carves a symbol on the back of the bathroom mirror, and collects a tissue with Jay's blood. Jay and Gal meet the client, who has a list of three people he wants killed. The employer unexpectedly cuts Jay's hand and his own, so that the contract is effectively signed in blood.
Their first target, captioned as "The Priest", recognizes Jay and thanks him just before being killed. The second name on the list, "The Librarian", is an archivist who keeps a collection of horrific, sickening videos of an undisclosed nature. Jay is deeply disturbed by the videos and breaks down in tears. As the duo enter the archivist's home, an enraged Jay beats him senseless and tortures him into identifying the videos' creators. As Gal goes to raid the safe, the archivist thanks Jay, who proceeds to savagely beat him to death with a hammer. In the archivist's files, Gal finds a folder on himself and Jay, including details of their Kyiv mission. Although they do not recognize it, the files include the symbol that Fiona carved in Jay's mirror.
Jay insists they kill the archivist's associates. Gal drives them to the location of the creators of the videos, where Jay brutally murders all of them. Gal informs Jay that, from the archivist's safe, he took enough money to cover the contract money. The pair decide to abandon the contract and return home. When his cut hand becomes infected, Jay visits his regular doctor, only to find he has been replaced by another man who will only give him cryptic advice.
Jay and Gal return to their client and offer to find replacements for the last hit. The client refuses and says that both hitmen and their families will be killed if they do not complete the contract. Shel takes their son Sam to the family's cottage for safekeeping while Jay and Gal go back to work.
Their final mark, "The MP", is a Member of Parliament who lives in a mansion. While observing the house, the pair witness a strange ceremony in the woods that culminates in human sacrifice. Jay opens fire with an assault rifle, and the leader of the ceremony presents himself for Jay to execute. He kills the leader and several cultists before the remaining masked members chase the hitmen into an underground complex. They capture and disembowel Gal, forcing Jay to perform a mercy killing on him. Emerging from the tunnels, Jay flees to the family cottage and meets with Shel. When he goes outside, he finds their car tires have been slashed and lit torches have been placed around the nearby field. Jay attempts to locate their attackers, but he is knocked unconscious. Inside the cottage, Shel arms herself and shoots several invaders.
Jay awakens in the field surrounded by the cultists, who strip him and place a mask over his face. He is confronted by his last victim, "The Hunchback", a masked and cloaked person armed with a knife. After a brutal knife fight, Jay triumphs, only to discover that the Hunchback was his wife with Sam strapped to her back. Shel laughs as they both die. The cultists applaud and remove their masks, revealing Fiona, the client, and the man from the doctor's office amongst their numbers. Jay is then crowned by the cultists.
