In Time is set in a dismal future in which the currency is time on or off one’s life. A cup of coffee costs like four hours or days or whatever the heck it was. Everyone has these watches with light-up numbers embedded in their arms. When they go to work, some time is added to their lives. They can exchange time, too, by doing this weird handshake thing.
Will (Justin Timberlake) stumbles upon a guy who has over a century on his arm. He says that he’s lived over a century and ends up transferring most of his remaining balance to Will who embarks on a quest to take down the system.
