Plot synopsis:
Joseph Smith (Jason Statham) is an ex-Special Forces veteran who went AWOL from his unit in Afghanistan, and now lives as a homeless drunk in London. One night while fleeing thugs who were shaking down the homeless, he breaks into an apartment and discovers the owner, a photographer named Damon, will be in New York for several months until the first of October. He begins to assume the life of the owner, driving his car and living in the apartment, calling himself Joey Jones, and spends his time looking for his homeless friend Isabel (Victoria Bewick), from whom he was separated in the streets. He finds Damon's new debit card in the apartment mail, and begins a regimen of self-improvement. Meanwhile, Isabel has been coerced into becoming a prostitute by the same thug that hassled her and Joseph.
Joey is friends with Sister Cristina (Agata Buzek), a Polish nun who runs the local soup kitchen, and she helps him with antibiotics for the wounds he received in the fight with the thugs and information on Isabel's whereabouts. To deflect suspicion of Damon's neighbors he tells them that he is Damon's boyfriend. To avoid using any more of Damon's money from the debit card Joey gets a job in a Chinese restaurant kitchen. One night at work the management call upon him to help deal with some rowdy diners, his fighting skills bring him to the attention of Mr. Choy (Benedict Wong), a senior manager in a London Chinese organized crime syndicate, who hires him as a driver and enforcer, collecting extortion payments and delivering drugs. He saves some of the money he receives and begins to do charitable work, ordering pizzas for the homeless at the soup kitchen and buying gifts for Cristina. The homeless begin calling him "Crazy Joe". He finds Dawn (Vicky McClure), his ex and mother of his young daughter, and starts giving her money.
Joey invites Cristina to dinner at a barbecue in the street behind the Chinese restaurant. Cristina attends, but only to show him a police photo of Isabel, who had been beaten to death and thrown in the river. Joey is enraged, but Cristina is able to calm him, and encourages him to start an honest life. He finds the street thugs who chased him away from Isabel and viciously beats them, interrogating them about Isabel's murder, acquiring a rough description of her killer. Joey meets Cristina at an art gallery showing off Damon's work, to give her this information to pass on to the police. She gets a bit tipsy, opens up to Joey, and they kiss. She tells him about a ballet ticket she has for the same date as when Damon is due to return – 1 October.
The police eventually learn of Joey's activities, and begin questioning Cristina. Joey finds her later, and they share life stories. As a child, she was sexually abused by her gymnastics instructor in Warsaw, and eventually killed him. Being too young for prison, she was instead sent to a convent. Cristina is ashamed of her relationship with Joey, and asks her mother superior (Ger Ryan) to be transferred to another mission in Sierra Leone. Joey continues his search for Isabel's killer, trading services with Mr. Choy's boss. He is given the keys to a truck with boxes containing Chinese victims of human trafficking to be delivered.
Meanwhile, Isabel's killer, Max Forrester (Christian Brassington) is savagely beating another hooker. A neighbor finds Max's invitation to a rooftop cocktail party, and the invitation finds its way to Joey, who had put the word out that he wanted information of someone fitting Max's description. The party is on the first of October.
Joey meets Cristina the day of 1 October. He asks her to take photos of him for his daughter, and he hints that he won't be the same for long. She tells him that she is leaving for Africa, and that she wants to be with him before she leaves; the last of her "crazy patch" she's going through, she says. The two consummate their relationship as the apartment's owner returns, and they escape through the back. She invites him to the ballet. He delivers the photos and a bag full of cash to his ex and daughter who does not recognize him.
Cristina waits for Joey, but he goes to the rooftop cocktail party instead. He finds Max Forrester and throws him from the roof many stories down in front of the guests, killing him. Cristina leaves the ballet, still looking for Joey. She finds him drunk and sleeping on the curb near the ballet theatre. He reveals that he is wanted by the military police for court martial for a random revenge killing he carried out in Afghanistan in payback for the deaths of five of his men, who were slaughtered in front of him in a tank. He often has random hallucinations of the innocent man he hanged and hallucinates hummingbirds; as thus was what the aerial drones in Afghanistan were designated. He explains to her that when he is sober and functional, he hurts people, because that is what his training turned him into. Joey tells her that he is going to return to life as a wandering drunk because that way he doesn't hurt anybody, but not before he gives the police information on Mr. Choy's human trafficking operation.
The next day, Cristina is leaving for Africa, and receives a note from Joey. He has paid his debts with everyone and is homeless again. As he walks the streets, the police are closing in, and he is hunted by a surveillance drone similar to the one that witnessed his crimes in Afghanistan: a hummingbird.
