October 1941. A ferocious battle on the North Atlantic of World War II is not going well for the Allies. Canadian Convoy SC42 is battling high winds, stormy seas, and German U-boats. Ships, men, and cargo are being lost at an alarming rate. HMCS Blackfoot, Canada's first Tribal Class Destroyer, answers the convoy's desperate call for help.|
For Blackfoot's Yeoman of Signals Matthew Brock, it is his first encounter with the U-boat and its ambitious commander, Lieutenant Klaus Hartenstien. While attacking the U-boat, Matthew is engulfed in a strange, blue light-Blackfoot is embraced by a malevolent fog. When released by the fog, Matthew determines that he has travelled back in time to the War of 1812-and so have the Germans.
From the streets of Boston in 1812, to the battlefield of the Niagara Peninsula, Matthew leads men from both the nineteenth and twentieth centuries in order to protect the continent's future-and the very existence of Canada and the United States.
