Captain America: Civil War 3D Overview

Tensions rise between Captain America/Steve Rogers (Chris Evans) and the other Avengers when global governments initiate an act to regulate all superhuman activity.

Iron Man/Tony Stark (Robert Downey Jr.) believes the superheroes should register, while Rogers believes in the principles of freedom and has a clear mistrust of the government. The events put a strain on the friendship and eventually, The Avengers.

Meanwhile, Steve meets up with an old friend, Bucky Barnes (Sebastian Stan), who's in trouble. He's accused of a crime he says he didn't commit, and his life is now in danger. Steve stands behind him, but the other Avengers believe his actions are putting them in danger - they ask him to disassociate himself from Bucky.
