Nemo is a young and cheerful clownfish who happily lives with his father, Marlin, in the Great Barrier Reef, and is eager to explore life around the ocean, but Marlin is overprotective of him, due to a barracuda attack that killed his wife, Coral, and the rest of their eggs years before, leaving him and Nemo as the only survivors. Nemo’s egg was damaged in the process and was born with a bad fin. On the first day of school, Marlin embarrasses Nemo during a field trip. When Marlin talks to the teacher, Mr. Ray, Nemo sneaks away from the reef and is abducted by a scuba diver, who puts him on a speedboat. Marlin gives chase and meets Dory, a blue tang who suffers from short term memory loss. The pair encounter three sharks named Bruce, Anchor, and Chum who are trying to not eat fish. While at their meeting, Marlin sees the diver’s mask that fell from the boat that took Nemo and also sees writing on it. However, Marlin and Dory fight over the mask, giving Dory a nose bleed. The blood sends Bruce into a feeding frenzy, and he attacks Marlin and Dory, who narrowly escape.
