Gun crazy 4: requiem for a bodyguard (2003)

In Southeast Asia, armed guerillas storm a party being hosted by a major Japanese trading company. They kidnap Eri Enomoto (Rika Uesugi), the director's daughter, and demand a huge ransom. But company infighting stalls plans to comply with the kidnappers, and Eri's father collapses from the strain. When Eri's childhood friend, Miki (Natsuki Katoh), learns of the kidnapping and the company's reluctance to save her friend, she decides to try and rescue Eri on her own.
