Samurai Girl is a six-hour miniseries loosely based on the popular young-adult novel series by Carrie Asai.
But 19 years later, things take an unexpected turn, when her wedding is attacked and her brother, Ohiko, is killed trying to save her, not before warning her that the Yakuza have infiltrated her family.
As she is trying to access her fathers files, she is discovered by the maid and takes off running with the laptop and is rescued by Jake.
When Heaven goes to the supermarket, she encounters a man named Severin, who tells her that he was building a case against her father and the Yakuza and asks her to return home.
Severin again meets up with Heaven to tell that her necklace was also a tracking device and that he needs her help to take down her father's empire.
With the help of Severin, Cheryl, and Otto, Heaven sneaks into her father's office and steals the documents about the prophecy.
After Severin reviews the text, he hands it to a former professor to have it translated: He tells her that a secret decoder written on a series of bones sits at the Japanese consulate.
Jake joins them but they discover that Sato and his men have started on the trail, so they climb up the face of Mount Kyra.
Heaven stays frozen until Severin orders her to climbing so that Jake wouldn't have died in vain.
After a botched sting operation to uncover Tasuke's money launderer, known only as Sonia, Karen stabs Sato and cuts herself to make it look like he escaped.
Meanwhile, Severin is interrogating Tasuke, who was arrested in a planned sting, during which he tells the history of the Morishi Protocol which included an underground bidding war.
At the end, on the way home, Heaven comes across Sato and is quickly surrounded by a gang of ninjas and she prepares to fight them.
On the second day of the 2008 San Diego Comic-con, the cast and crew promoted the movie by signing autographs and participated in a question and answer session with attendees.
