Sister Street Fighter

Lee Long, a shorinji kempo champion and Hong Kong drug agent, vanishes while pursuing leads into the dummy corporation Central Export. Tina Long, his sister, is summoned to continue the investigation and uncover the truth behind his disappearance.

On the trail of clues, Tina stops by her uncle's restaurant to gather information and check in with family. She reconnects with her cousins Jerry and Remi, keeping focus on Lee's case as she continues forward.

At Club Mandarin, Tina receives a red rose—the signal to look for Fanny Singer, Lee's partner in the investigation. The gesture marks a shift from searching for Lee to pursuing those tied to the case.

Assassins for Central Export abduct Fanny while Tina fights them, but the group overpowers Tina and loads Fanny into their car. The abduction escalates the danger surrounding the investigation and sets up a chase.

The car carrying Fanny is hijacked by shorinji kempo student Sonny Hibachi, who drives her toward Shinobu Kojo's ballet studio. The detour places Fanny in a precarious location and advances the pursuit of Lee's whereabouts.

At Kojo's ballet studio, Tina questions Fanny, who confirms that Lee is being held captive. Fanny offers a necklace before succumbing to a poison dart during a coordinated assault, leaving Tina more determined to push forward.

Some time later, Emmy Kawasaki swears allegiance to Tina and assists in the investigation. She discovers a lock of hair—another clue linking the case to Central Export and its operations.

Central Export leader Kaki offers Hammerhead a substantial reward to eliminate Tina. The warning to Tina's allies signals that the organization is escalating its efforts to remove her from the equation.

Tina confronts Hammerhead on a bridge in a tense fight. Hammerhead reveals that Lee is alive and imprisoned in Kaki's dungeon before attempting to push Tina into the water, a signal of the dangerous game she is entangled in.

Emmy leverages her espionage to help Tina uncover and destroy a warehouse owned by Central Export. The destruction weakens the organization's material network and narrows Tina's path forward.

Central Export launches an ambush on the shorinji kempo school; Sonny defends the place and faces Hammerhead in a decisive one-on-one duel. Sonny's skill keeps the attack at bay, stalling Hammerhead's plans against Tina.

Kaki uses Tina's uncle to seed a false lead, leading Tina back toward his restaurant. She arrives to find her uncle dead from a poison dart, an act witnessed by Jerry and Remi that intensifies Tina's resolve to end Central Export.

Tina returns to Central Export and infiltrates the dungeon, freeing Lee just as a sinister minister shoots him with an arrow gun. Tina is then dropped into a pit and nearly killed when Kaki ties her above a bed of spikes.

Tina breaks free from the spike trap, destroys more enemies, and fights Hayashi, killing him by twisting his neck. With backup from Sonny, Emmy, and Kojo, the final assault continues and Tina corners Kaki, killing him with his own claw hand as the remaining minions fall.
