On a trip to Bangkok, an American businessman finds himself out of his depth when he inadvertently crosses the border in Vietnam.

The Sword of Bushido tells the story of ex-Navy SEAL Zac Connors and his journey to learn the fate of his grandfather, who mysteriously disappeared days after the end of World War 2, with a legendary stolen Japanese sword in his possession. With the help of a stunningly sexy computer analyst (who he ends up sleeping with, the suave dog), he learns that his grandfathers' plane crashed somewhere on the outskirts of Thailand.
