 A clown fish named Marlin living in the Great Barrier Reef looses his son, Nemo after he ventures into the open sea, despite his fathers constant warnings about many of the Ocean s dangers, is abducted by a boat, and netted up and sent to a dentist s office in Sydney. So, while Marlin ventures off to try and retrieve Nemo, Marlin meets a fish named Dory, a blue tang suffering from short-term memory loss. The companions travel a great distance, encountering various dangerous sea creatures such as sharks, anglerfish and jellyfishes, in order to rescue Nemo from the dentist s office, which is situated by the Sydney Harbor. While the two are doing this, Nemo and the other sea animals in the dentist s fish tank plot a way to returning to Sydney Harbor to live their lives free again.
