The year is 1900.
"Three young doctors celebrate their graduation from medical school with a dinner on the San Francisco docks…until they’re kidnapped and Shanghaied to China. The doctors’ families are rich, and they entice Vice President Teddy Roosevelt into organizing a secret, rescue mission. Teddy dispatches his former Cuban War veteran officer, Major Gunther from the Philippines to run the top-secret mission, but not without first destroying the rotten shanghai operation on the bay."
