The first season of Teenage Mutant Ninja Turtles introduces the four turtles Leonardo, Donatello, Raphael and Michelangelo. On their first trip to the surface, the Turtles witness a young girl named April O';Neal and her father being kidnapped by a group of people who call themselves the Kraang. When a video surfaces showing the Turtles topside, Master Splinter worries that their secrecy will be compromised. Meanwhile, Raph loses his temper when he is insulted by a caustic New Yorker named Vic, who videotaped the Turtles and threatens to expose them to the world.
