Contract killer Shuji Kamimura (Joe Shishido) and his partner Shun Shiozaki (Jerry Fujio) are hired by yakuza boss Senzaki to eliminate a former partner, Boss Shimazu, who has embezzled from an international co-op between both men. Kanimura successfully assassinates Boss Shimazu at his home while meeting with Senzaki. Kanimura and Shun attempt to leave the country by plane, but are waylaid and kidnapped by Shimazu's men. After causing their car to crash (thanks to a specially-designed second brake behind the driver's seat that Shun had installed earlier), Senzaki's lieutenant Nozaki orders them to hide out at a truck stop, the Hotel Nagisakan, to wait for further instructions. Later that night, more gunmen under Shimazu's lieutenant, following information from fellow yakuza boss Tsugawa arrive to kill them, but do not find the duo as they have escaped by bribing one of the patrons to take them to another motel.
