Dimension 5

Power returns from a mission using a time-travel belt to steal secret plans. He is instructed by Cane to team with a Chinese agent to counter Dragon, a crime lord led by Big Buddha. Dragon intends to coerce the United States by threatening to destroy Los Angeles unless forces are withdrawn.

Chang is subjected to a truth machine at Espionage, Inc. headquarters. He reveals that Dragon has a primitive hydrogen bomb being delivered piece by piece to Los Angeles, with a Christmas Day deadline three months away. The interrogation outlines the scope of the threat and the race to stop Dragon.

Power meets Ki Ti Tsu, the agent assigned to partner with him. She joins the mission and helps plan the next moves against Dragon. The new partnership broadens their capability to counter Dragon's network.

Power and Kitty visit Kim Fong's Cantonese restaurant to learn about the Dragon black market. The hostess, Nancy Ho, who is a Dragon agent in disguise, pressures Fong to hand over a bomb disguised as an owl-shaped incense burner. Kitty's suspicions grow as she notices the hostess's duplicity.

The owl bomb detonates during the ensuing confrontation; Nancy Ho is killed by Kitty as she attempts to stab Power. Kitty's subsequent actions appear to hand Power over to Dragon, but she has her own reasons and signals headquarters for a rescue. Power is liberated, and the mission continues.

Power demonstrates the time travel belt to Kitty, explaining its limits and risks. He warns her to only travel to places that will still exist in the future or past and cautions against altering timelines. They reaffirm their resolve to complete the mission without relying on the belt.

Cane informs them that Ming company, a front for Dragon and the maker of the owl bomb, has a warehouse in Long Beach. A shipment from Hong Kong aboard the Osaka Maru is due in three weeks. Power and Kitty plan to intercept the operation by using the time belt to jump ahead three weeks.

Power and Kitty jump three weeks into the future to inspect the warehouse and locate the bomb. They move carefully, aware Dragon agents are watching, and try to avoid detection. Stoneface attempts to kill them with a disintegrator, but Big Buddha kills Stoneface instead.

Inside the warehouse they discover Uranium-238 among Christmas decorations. Dragon's forces close in, forcing Power and Kitty to evade capture by darting between barrels in a limited travel space. Big Buddha arrives and the chase intensifies.

Kitty confronts Big Buddha about his war crimes, including the Nanking massacre, and is captured in the struggle. Power surrenders to Buddha to save Kitty, inviting a potential exchange of secrets. Buddha plans to ship Power to Hong Kong to extract information.

The mute servant girl makes another attempt to stab Buddha, seizing the moment to strike. Power uses the distraction to turn on Buddha's bodyguard, Genghis, and a brutal fight ensues with the odds stacked against Power. Kitty throws Power a gun, and he shoots Genghis; the servant girl finishes Buddha off.

Power and Kitty return to the present with new knowledge to counter Dragon without further time travel. They coordinate with Cane's team so Dragon's threat can be stopped through conventional means. Los Angeles is spared as the operation shifts to a non-time-travel strategy.
