Hancock

John Hancock is a homeless guy who possesses superpowers residing in Los Angeles; he is also an alcoholic and a vigilante notorious for causing severe damage while fighting crimes.

Ray Embrey, a public relations spokesman, is trapped in his car on a railroad. when a freight train is about to hit him, Hancock saves his life, but the locomotive is destroyed and the train is derailed. while the crowd are complaining about Hancock's reckless act, Ray sticks up for him and invites him over for dinner. To thank Hancock for rescuing him, Ray offers to help him to improve his public image, and Hancock reluctantly agrees.

The authorities put him in jail for destroying public property. With Hancock in jail, crime rate has been increasing. Eventually, the chief of police contacts him for help. Wearing a costume made by Ray, he arrives at a bank robbery scene, causing little damage, saving a injured policewoman, subduing the mastermind of the criminals, Red Parker. The crowd applaud when he comes out.

Hancock, Ray and Mary(Ray's wife) go to a restraunt to celebrate, and Hancock reveals his amnesia and immortality. After putting a drunken Ray in his bed, Hancock finds out that Mary is of his own kind. He asks her about their origin, but Mary is unwilling to tell. After he threatens to let her husband know, she tells Hancock that they were a couple, but when being together, their superpowers disappear and they become mortal.

At a grocery store, when trying to stop a robbery, Hancock is shot in the chest(he used to be invulnerable), and sent to a hospital. Mary shows up at the hospital, and they share an intimate moment. Red Parker, who has escaped from the prison with his minions, arrives at the hospital to seek revenge. A fight ensues; Mary is shot dead; Hancock is knocked to the ground. Although Ray saved him from being killed by Red, Hancock died anyway. But he resurrects and jumps out of the hospital in order to stay away from Mary, because it's the only way they can live.

Later, Hancock is seen in New York, he paints a All-Heart logo on the moon to pay homage to Ray. Mary and Ray are reconciled; the cast starts rolling.
