The 50 minute film tells the story of one of Canada's finest amateur baseball teams prior to World War II, the Asahi team. This team, which was composed of all Japanese-Canadians, was a nearly unbeatable squad in British Columbia.
After the bombing of Pearl Harbor, the Canadian government (which had already been at war with Japan) decided to relocate all people of Japanese descent from the West Coast. This decision actually predated the U.S. government's decision to do likewise. The Asahi team members were forced to move east or move to internment camps and few, if any, moved back to British Columbia after the war.
It's a fascinating story and well worth investing an hour of your time in watching.
Here's a question for you: When were people of Japanese descent allowed to vote in British Columbia Provincial elections? The answer is here. You may find it surprising.
