The controls and wheel move my themselves.Aboard the cruise ship, the prickly Captain Ashland (George Kennedy) is making his final voyage, attended by his replacement, Captain Trevor Marshall (Richard Crenna), who has brought along his family. Outside, the freighter heads right for them, blasting its horn, and despite Ashland's best efforts, collides with the cruise ship, sinking it.The next morning, a handful of survivors, including Marshall, his wife Margaret (Sally Ann Howes), their children Robin and Ben, a young officer named Nick (Nick Mancuso), his love interest Lori (Victoria Burgoyne), the ship's stand up comic Jackie (Saul Rubinek), and a passenger, Mrs. Morgan (Kate Reid), are adrift on a large piece of wreckage. Ashland surfaces nearby, and is brought aboard barely conscious. Later, the survivors come upon the black freighter, unaware it is the ship which attacked them. Finding a boarding ladder slung from the stern, they climb aboard, but not before the ladder plunges into the sea as the officers try to climb it with the injured Ashland. When all are finally aboard, Jackie tries to rally the survivors with humor, but a cable seizes him by the ankle, and he is lifted and swung outboard by one of the ship's cranes, which lowers the thrashing comic into the water before cutting him loose, to be swept astern and lost.Shocked, the survivors explore the corridors of the empty, echoing vessel, finding only cobwebs and 1930s memorabilia. Hatches open and close by themselves and lights go on and off while a swinging block knocks out Nick, who is exploring above deck.Meanwhile, a delirious Ashland hears a disembodied voice speaking to him in German, telling him: "This ship has been waiting for you...It is your new ship....Your chance has come!" The others finally set up in a dusty bunk room, and break up to retrieve...???

input question: Generate a question that has the following answer: unsure for the following movie plot: Deep Impact opens to a starry night sky in Richmond, Virginia. The camera slowly pans down where stargazers and amateur astronomers are gathered with telescopes. Among these are students and faculty of the Lee High School Astronomy Club. Two students at this club are Leo Beiderman (Elijah Wood) and his girlfriend, Sarah Hotchner (Leelee Sobieski). As they look through their telescopes at the stars, Leo innocently asks Sarah about another male student who invited her to a student party.Leo and Sarah's teacher, Mr. Perry (Mike O'Malley) comes up and quizzes them about some of the brighter stars. Leo correctly identifies the stars Mizar and Alcor, but cannot name a somewhat smaller, dimmer star a bit south of the other two, although he is sure that it is not the star Megrez, as Sarah claims. Mr. Perry, thinking it might be a satellite, suggests they take a photograph and send it to Dr. Wolf, a professional astronomer who sponsors the Lee High School Astronomy club. As Perry walks away, Leo and Sarah get into a brief, teasing argument about whether the unidentified star is Megrez.Dr. Marcus Wolf (Charles Martin Smith, uncredited) arrives for work at the Adrian Peak observatory in Tuscon, Arizona. Seating himself at his work station, he finds the packet sent him by Leo, containing a photograph of the unknown star near Mizar and Alcor, and a cover letter asking him to identify it. Punching the stellar coordinates into his computer, he sees it is an uncharted object. His observatory's telescopes zooming in on it, he sees it is in fact a comet. Curious about it, he directs his computer to analyze the comet's position and calculate its trajectory. As the numbers begin to scroll through the screen, Dr. Wolf's curious expression fades into a look of severe worry and concern. An orbital interpolation graphic on his monitor overlays the comet's projected path on a small display of the solar system-- and a large dot quickly appears on the third elliptical line around the sun's icon; the comet is projected to strike...???

They vanish after rescuing Keno, tying up the burglars, and taking the pizza he was delivering, leaving money to pay for it. Leonardo, Donatello, Michaelangelo and Raphael, along with their master Splinter, are living with April O'Neil while they look for a new place to live following the events of their last adventure.

At a junkyard where the remnants of The Foot and Shredder's second-in-command Tatsu are hiding out, they are met by their master, who has been disfigured by his previous defeat but did not die as they thought. April interviews Professor Jordan Perry of Techno Global Research Industries (TGRI) about a possible toxic waste leak. He assures her that everything is fine, but at the same time their scientists discover dandelions which have been mutated by the contaminant. Freddy, a spy for the Foot posing as April's cameraman, discovers this and reports it to his master, who decides to have Perry interrogated. Back at April's apartment, Splinter reveals to her and the turtles that TGRI was responsible for their mutation more than fifteen years prior, and they too decide to talk to him. The Foot gets to Perry first and kidnaps him, salvaging the last vial canister of ooze in the process. The turtles attempt to get the canister back, but ultimately fail. Afterward, Keno gets into April's apartment under the guise of delivering pizza and discovers Splinter and the turtles. At the Shredder's hideout, Perry is forced into using the remaining ooze on a wolf and a snapping turtle, which mutate into Tokka and Rahzar.
