Plot
In the aftermath of Hitman: Blood Money, Diana Burnwood, Agent 47's handler with the International Contract Agency, suddenly goes rogue, carrying out a catastrophic sabotage that includes publicly exposing the Agency. The Agency reforms under agent Benjamin Travis; Travis assigns 47 to kill Diana and bring Victoria, a teenage girl in her care, to the Agency. Shooting and wounding Diana in her home in Chicago, 47, rather than executing her, comforts the seemingly dying Diana, who gives him a letter and asks him to keep Victoria safe from the Agency.47 hides Victoria at a Catholic orphanage, somewhere in Chicago and contacts an informant named Birdie, who asks him to kill a wealthy gangster nicknamed 'The King of Chinatown'. After eliminating him, 47 meets with Birdie, who briefs him about Blake Dexter, the CEO of Dexter Industries, who may have more information on Victoria. As payment, 47 is forced to give his Silverballers to Birdie. 47 learns that Dexter is in the 'Terminus' hotel and after evading Dexter's henchmen, eavesdroppes on him. 47 learns from Dexter's conversation with his secretary Layla that he plans to kidnap and auction Victoria to the highest bidder. 47 attempts to strangle with a wire Sanchez, Dexter's enormous bodyguard, who proceeds to knock 47 unconscious. Framed by Dexter for the murder of an innocent maid, 47 escapes the hotel that was set on fire because of Dexter and evades the police. 47 contacts Birdie, who tells him to go to a local strip club and kill the owner Dom Osmond, who works as an informant for Blake Dexter, so that he can protect Victoria. 47 kills Osmond and learns from a phone message in his office that Birdie is being hunted by Edward Wade - a psychopathic mercenary, who is a close friend of Dexter and is under his employ. Despite killing henchmen that were looking for Birdie, Birdie still sells Victoria's location to Wade so that he can save his life. 47 reaches Victoria and learns that Victoria has a necklace that keeps her physically strong. Wade and his henchmen raid the orphanage and massacre most of the staff. 47 is forced to pick up fuse boxes that are scattered across the orphanage, since the elevator to the basement breaks down. After evading the henchmen, 47 installs the fuse boxes and starts the elevator. Despite 47's efforts, Victoria is kidnapped by Wade. 47 manages to shoot Wade, but Victoria is then taken hostage by Lenny, Dexter's son. 47 interrogates Wade to reveal Victoria's location - Hope, South Dakota - and leaves him to die of his injuries. Meanwhile, Birdie approaches Dexter, offering to broker the ransom of Victoria back to the agency, but he is rejected. In anger, Birdie secretly provides information about 47's location to the Agency, and information about Dexter to 47, hoping to profit off the situation. After arriving in Hope, 47 retrieves his Silverballers after Birdie informs him of their location at a gun store. Later, 47 kills Lenny's gang and interrogates Lenny. The player then drives him to the desert, and the player can either kill him or leave him in the desert. Learning from Lenny that Victoria is at Dexter Industries HQ, 47 infiltrates the facility and destroys their research data on the girl while assassinating its head scientists, and discovers that Victoria is in fact a genetically engineered clone, bred to be a top-class assassin like him, however her fighting skills are only possible when she wears her necklace. 47 kills Sanchez in an underground cage fight after learning from him Victoria was taken back to Hope. Recuperating at a hotel, 47 survives an ICA attack led by the elite nuns in leather outfits, the hit team 'The Saints,' and kills them.
Infiltrating Hope Courthouse Jail, 47 reaches Victoria but is subdued by the corrupt local sheriff Clive Skurky, who is working with Dexter. The ICA, led by Travis, takes over the town in an attempt to get Victoria back and kill 47, but she is nowhere to be found, while 47 escapes the prison and evades the ICA. He then confronts a wounded Skurky in a church, demanding Victoria's location. Skurky tells 47 she is at Blackwater Park, then dies from his wounds. Travis pays a ransom of ten million dollars for Victoria, but Dexter doesn't keep his side of the bargain and keeps both Victoria and the money. 47 arrives at Dexter's penthouse and kills Dexter's assistant, Layla. Dexter, unbeknownst that Layla has been killed, plans to destroy the hotel's roof if she didn't meet him there within five minutes. As Dexter is about to leave the hotel with Victoria and the money by helicopter, 47 mortally wounds him. 47 saves Victoria, while Dexter, with his dying words, apologizes to his son, Lenny and asks for his money. Victoria, who is disgusted by Dexter's words, opens the briefcase containing the ransom and throws the money onto his dying body. 47 and Victoria then leave the hotel.
47 learns from the letter Diana gave to him that Travis created Victoria without the Agency's knowledge; in the letter, she also requests that 47 kill Travis to protect Victoria. Pursuing him to England, 47 finds the ICA exhuming the Burnwood family graves, believing Diana's death to have been faked. After killing Travis' assistant Jade and then his personal guards, 47 corners Travis, who asks him if Diana is dead, but he refuses to answer him and kills Travis.

During a closing cutscene, 47 watches Diana and Victoria from afar, before a message from Diana welcomes him back to the Agency, revealing that the shot 47 fired at her was non-lethal. Victoria also considers disposing of her necklace to prevent her from hurting anyone, with Diana telling her to do what she has to. Another cutscene then shows Birdie offering information on 47 to Cosmo Faulkner, a detective investigating his case.
