Hancock, played by Will Smith, is a superhero with a bad reputation. He is often drunk and causes more damage than he prevents. Despite his powers, most people see him as a nuisance rather than a hero.
One day, Hancock saves the life of a PR expert named Ray Embray, played by Jason Bateman. In gratitude, Ray offers to help Hancock improve his public image. The two work together to try to rehabilitate Hancock's reputation, but their efforts are met with scepticism and hostility from the public.
As a last-ditch effort, Ray comes up with the idea of having Hancock go to jail for a while, hoping that the world will miss him and appreciate him once he returns. While in prison, Hancock encounters a man named Red, played by Eddie Marsan, who seems to know something about his past.
When Hancock finally returns, he is greeted as a hero. However, things are not as they seem, and he soon discovers that Red has an agenda of his own. As a result, Hancock must choose between his new-found sense of purpose and his old reckless ways.
Overall, Hancock is an action-packed superhero film with a unique twist. It explores the consequences of using superpowers irresponsibly and the importance of redemption.
