Disney’s cartoon, Finding Nemo, tells a touching story of a father called Martin and his son Nemo.

Martin loses his wife and an entire family of unhatched eggs to a huge shark. Only one fish egg remains, Nemo. Martin promises his dead wife that he will protect his young son at any cost. So, Martin becomes fearful of almost everything in the ocean. That makes him over protective-he hopes to keep his kid safe from the challenges that life presents. Martin’s nagging (唠叨) makes Nemo feel that he doesn’t need his dad telling him what to do.

So on his first day of school, Nemo and some friends swim to the edge of their coral reef, a place Martin always thinks is very dangerous. When Martin shouts at Nemo come back, Nemo refuses to listen to him and swim out to a boat in the distance. Suddenly, he gets caught by some divers. So begins Martin’s journey to find Nemo, who ends up in an aquarium in an office in Australia. Soon the worried father runs into Dory, a forgetful blue fish, who helps Martin find his son. Meanwhile, Nemo misses his father terribly. He soon hears that he will be given to an eight-yearold girl who likes to kill fish.
