Macy, the daughter of a Hong Kong banking
tycoon, plans to marry her fiancé, Takahashi Yuji, in the United States. However, on the day of their wedding, Takahashi fails to show up. Disappointed and confused, Macy travels to Tokyo in search of him. On the flight, she encounters architect Pat Tai-yung, who designed Takahashi's new home. Claiming he is chasing an unpaid debt, Pat follows Macy to Japan. To their shock, not only do they fail to find Takahashi in
Tokyo, but they also find themselves under attack by
yakuza thugs. Fortunately, whenever Macy and Pat find themselves in danger, private detective Lam Kwai-Yan mysteriously appears to save them. Lam later reveals to Macy that Takahashi has been targeted by the yakuza after getting involved with the wife of the powerful crime boss Ito Takeshi. As the three join forces to search for Takahashi, a critical mistake by Lam puts them on the radar of the yakuza. Faced with an unexpected series of twists, she is left feeling lost, disappointed by Takahashi's apparent betrayal yet still deeply worried for his safety. With no other choice, Macy agrees to cooperate with Lam to track down Takahashi and confront him in person. However, as time passes, she begins to realize that Lam's true identity is not as simple as he claims, and even Pat, who has been by her side all along, seems to have his own hidden motives. ==Cast==
