IMDb - Set in a world where people stop aging at 25, but are genetically-engineered to live only one more year, having the means to buy your way out of the situation is a shot at immortal youth. Here, a young man (Timberlake) accused of murder goes on the run with a hostage (Seyfried), though their eventual connection becomes an important part of the way against the system.
