Stosh should have figured that the FBI would find him eventually. Now they've turned up on his doorstepand they know all about his ability to travel through time using baseball cards. In fact, they want to send him back in time on a mission: to warn President Roosevelt about the attack on Pearl Harbor! But when Stosh finds out that his "ticket" to 1941 is a Ted Williams card, he starts planning a mission of his own. Williams is one of the greatest hitters of all timeeven though he lost almost five years of his career to serve in the Marines. How many more home runs would the Splendid Splinter have hit if he had those years back? What if Stosh can prevent the attack on Pearl Harbor and convince Williams not to serve in the military?
