It is 1941 and the world is in the throes of war. Sonic The Hedgehog (Jason Griffith) wants to do his part and join America’s armed forces, but the military rejects him because of his small slature. Finally, Sonic gets his chance when he is accepted into an experimental program that turns him into a supersoldier called Captain Sonic. Joining forces with Shadow the Hedgehog (Keanu Reeves) and Amy Rose (Lisa Ortiz), Captain Sonic leads the fight against the Nazi-backed HYDRA organization.
