Question: Who is leading the police Title: Blood Beach Movie plot: In the opening scene, a woman named Ruth is walking her dog on Los Angeles, California's Venice Beach, and is suddenly pulled under the sand of the deserted beach by an unseen force. The woman's screams for help are heard by Harry Caulder, a harbor patrol officer who is swimming nearby. Harry reports Ruth's disappearance to two LAPD detectives, Royko and Piantadosi, who claim that without a body, there is little they can do. The next day, Ruth's estranged daughter, Catherine, arrives from San Francisco after Harry calls her regarding her mother's disappearance. Meanwhile, the mysterious and crazed Mrs. Selden, who resides in an abandoned section of the Santa Monica Amusement Pier, witnesses the attack and disappearance (and others throughout the film), but does not come forward. That night, while staying in Ruth's house, Catherine hears Ruth's dog barking on the beach near the location where Ruth disappeared. Catherine investigates and finds the dog beheaded, near a small sinkhole. Royko and Piantadosi, as well as Harry, are called to the scene, but police pathologist Dr. Dimitrious cannot accurately determine a cause of death for the dog. Royko and Piantadosi believe it to be the work of a serial killer, due to reports of other disappearances over the past few months. The next morning, a teenage girl is buried in the sand at the beach, and begins screaming. Her friends pull her out of the sand, only to see that her legs have been injured from an attack by an unseen creature. The police, led by Captain Pearson, begin an investigation by digging up various sections of the beach at night, but find nothing. The next morning, people visit the beach, which the local media have dubbed "blood beach". The following night, Harry's co-worker Hoagy is closing up the harbor patrol office for the night when his girlfriend ventures under the pier to investigate a noise and is assaulted by a man. After being knocked to the ground by the girl, the would-be-rapist is attacked by the unseen creature, which castrates him. An...

Title: Piranha 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...

Title: Lethal Weapon 4 Movie plot: Lorna Cole (Rene Russo) is pregnant with LAPD Sergeant Martin Riggs' baby; they are not married, but both are thinking about it. LAPD Sergeant Roger Murtaugh's daughter Rianne (Tracie Wolfe), is also pregnant, though he is not told the child is with Detective Lee Butters (Chris Rock) since he did not want his daughter to marry a police officer. Due to issues with the department's insurance carrier over Riggs and Murtaugh's actions as sergeants, Captain Murphy (Steve Kahan) promotes them to captains. The officers along with Leo Getz (Joe Pesci) come upon a Chinese immigrant smuggling ring after running an ocean-going vessel aground. The captain of the boat escapes. In the subsequent investigation, Murtaugh finds Hong (Eddy Ko) and his family hiding from US Immigration officers to avoid deportation. Murtaugh offers them shelter in his home, and their families, along with Riggs and Cole, quickly bond. Hong reveals he is looking for his uncle, a skilled engraver, who had paid for their passage to the United States. Continued investigation of the smuggling ring leads the officers to "Uncle" Benny Chan, a crime boss operating from a Chinatown restaurant. There, they are introduced to high-ranking Triad negotiator Wah Sing Ku (Jet Li). Chan forces them out of his restaurant when the officers show no probable cause. Outside, Riggs spots the escaped captain and tries to give chase but fails to capture him. However, Ku later intercepts the captain and kills him as punishment for attracting the police attention. Chan and Ku take steps to eliminate all those in on their plans. Hong is able to contact his uncle, but this leads the Triads to Murtaugh's house. Ku and the Triad thugs kidnap the Hongs, tie up Murtaugh, his family, Riggs and Cole and set the house ablaze. Ping, Hong's son, had evaded capture and helps to free the others in time.
