Steve Rogers woke up in the 21st century and to a world full of modern technology and changes. He's still not comfortable about his new life except when he is Captain America. When S.H.I.E.L.D. learns HYDRA agents are on the rise and threatening the world's safety, Nick Fury calls on Steve to suit up and put an end to HYDRA's evil plans. But even the courageous Captain America isn't ready for HYDRA's new leader, Armin Zola, Cap's old foe resurrected as a powerful robot, and his plan to build a robotic army of Super-Soliders known as The Tomorrow Army to take over the world and destroy Captain America and SHEILD once and for all. Outmatched, Steve must now rely on help from others-namely Black Widow and Falcon-to face the thing he doesn't understand: a techno-villain who is twisting modern technology to his own evil purposes. The world's only hope is the courageous Captain America!
