Q: Generate a question that has the following answer: Vivian Shang for the following movie plot: Kitty (Chingmy Yau) is a vicious young woman who has no qualms about stabbing girlfriend-bullying men in the genitals. Tinam (Simon Yam) is a cop who is undergoing a rather traumatic period: he shot his own brother by accident and as a result vomits every time he handles his gun. When Kitty severely injures a man by stabbing him in the groin, Tinam attempts to arrest her but fails. Kitty later turns up at the police station and manipulates the facts to the point that Tinam has no choice but to start a relationship with her. This reveals Kitty as a subtle manipulator. Tinam, who has become impotent, finds that he no longer feels the same way about Kitty, who is content with leading him on. Kitty's father is married to a new wife but the marriage is tense. One evening he catches her cheating on him with another man called Bee (Ken Lo). In the fight that follows, Kitty's father falls down the stairs and is killed. Furiously determined to seek revenge, Kitty breaks into Bee's office and proceeds to kill him, his bodyguards and most of his staff (there is some indication that he is involved with organised crime). In the course of her escape she takes a woman hostage but, unexpectedly, the woman helps her out, disposing of many of the pursuers herself. The woman turns out to be Sister Cindy (Wai Yiu) who is in fact a professional assassin. She was out to kill Bee herself before Kitty intercepted. Seeing that Kitty has potential, she proceeds to train her and gives her a new identity. The training includes the killing of enraged, chained-up paedophiles in Sister Cindy's cellar. Before long, the pupil outsmarts the teacher. For her first mission, Kitty accompanies Sister Cindy and murders a member of the Japanese yakuza. This leads to a contract being placed on them and the assignment is entrusted to Princess (Carrie Ng), one of Sister Cindy's former proteges and a lesbian with an equally deadly young lover called Baby (Madoka Sugawara). While investigating the murder himself, Tinam goes to check up on an air...

At the same time, Chris Higgins and her friends return to Higgins' Haven to spend the weekend.

Rick loses his temper after seeing the window of his Volkswagen Beetle smashed in and leaves with Chris. Meanwhile, Jason has hidden in the barn to recover from his injuries, and when the bikers show up to siphon their gas with the intention of burning down the barn to get even, he kills Loco and Fox with pitchforks and seemingly kills Ali with a pipe wrench.

Question: Generate a question that has the following answer: Water park for the following movie plot: Two teenagers come upon an apparently abandoned military installation. They take advantage of what appears to be a swimming pool to skinny dip. The teenagers are attacked by an unseen force and disappear under the water. A light activates in the main building and a silhouetted figure investigates the screams, but is too late to help. A determined but somewhat absent-minded insurance investigator named Maggie McKeown is dispatched to find the missing teenagers near Lost River Lake. She hires surly backwoods drunkard Paul Grogan to serve as her guide. They come upon the abandoned compound, which functioned as a fish hatchery before being militarized. They discover bizarre specimens in jars and indications of an occupant. Maggie locates the drainage switch for the outside pool and decides to empty it to search the bottom, but the moment she activates it a haggard and frantic man begins to panic and attacks her, attempting to stop the draining until he is subdued by Grogan. The two found a skeleton in the filtration trap of the empty pool, and learn it was filled with salt water. The man awakens and steals their jeep, but crashes it due to his disorientation, and is taken to Grogan's home where they spend the night. They take Grogan's raft down the river, where the man wakes up and tells them that the pool in the facility was filled with a school of piranhas, and that Maggie released them. They are skeptical until they hear a dog barking and they come across the corpse of Grogan's friend Jack, who has bled to death from an attack on a fishing dock. The man reveals himself to be Doctor Robert Hoak, lead scientist of a defunct Vietnam War project, Operation: Razorteeth, tasked with engineering a ravenous and prodigious strain of piranha that could endure the cold water of the North Vietnamese rivers and inhibit Viet Cong movement. The project was shut down when the war ended, but some of the mutant specimens survived, and Hoak tended to them to salvage his work. Grogan realizes that if the local dam is opened, the...
