The year is 1966. S.H.I.E.L.D. sends agent Ran Shen to collect two Nazi scientists with the key to winning the Cold War. But the Soviets want the scientists as well, and they've unleashed their most dangerous operative: the Winter Soldier, aka Captain America's brainwashed and presumed-dead partner Bucky Barnes! His mission: acquire the scientists by any means necessary - or kill them. The only obstacles in the Winter Soldier's way are an elite Hydra squad run by Chancellor Cassandra and Madam Worm - and his own returning memories!
