The story begins with an underachieving fish named Oscar (Will Smith) going to work and slipping up with a mistake again. With that, he is called to his boss', Mr. Sykes (Martin Scorsese), office to discuss the fact that he owes money and has to pay it back by the next day. As he explains to his best friend, Angie (Renée Zellweger) (who harbors a secret love for him), he is offered the chance to pay back the money by pawning off a pink pearl given to him by her, which he plans to use, but is distracted by his wishes of grandeur and places it all on a bet at the race tracks. The race is lost and Oscar is set to be surreptitiously killed.
Meanwhile, on another side of the ocean, a family of criminally-inclined sharks has a trouble with one of their sons, Lenny (Jack Black). Lenny refuses to act the part of a killer and wishes to not have to live up to those expectations. With this, his father, Don Lino (Robert De Niro), decides that he must learn to kill, by being taught by Lenny's more savage brother, Frankie (Michael Imperioli).
As the two sharks set out to go in accordance with their father's wishes, Frankie spots the scene where Oscar is being electrocuted by Ernie and Bernie (Doug E. Doug & Ziggy Marley), his boss' two jellyfish thugs and sends Lenny off to attack. The jellyfish spot Lenny and swim off, leaving Oscar alone with him. Lenny tries to calm Oscar down by telling him that he will not eat him, but Oscar will not listen, and insists on screaming, until Frankie becomes annoyed and tries to attack, but an anchor kills him. As no one saw the deed done and Oscar was seen near the body, everyone thinks he did it, and Oscar saw the chance to both redeem himself and receive his fame.
Oscar comes back to the city with a new title of the Sharkslayer. On the way he meets Lenny once more who forces Oscar to let him stay with him because he does not want to go home. Soon Angie finds out about the lie and threatens to tell everyone but Oscar keeps her satisfied. Meanwhile while it obvious that Angie loves Oscar, Oscar has fallen in love with gold digger Lola (Angelina Jolie).
Although Oscar desires to please everyone, he soon discovers that he pleases no one; his paramour Angie is heartbroken by the fact that Oscar is no longer honest, while her hedonistic rival Lola is disgusted by what she considers low taste. Don Lino plans revenge, and Oscar must rise to the occasion. When the trick planned by Oscar and Lenny succeeds only in angering Don Lino, Oscar lures both sharks into a trap. Given an ovation by the other fish, Oscar confesses that he is not a real "Sharkslayer". He forsakes all the wealth he has acquired, makes peace with the sharks, and marries Angie. However, he becomes manager of the Whalewash. Lola also ends up with a crazy crab. Moreover he helps Don Lino make peace with Lenny.
Christina Aguilera and Missy Elliott make a cameo appearance in the end of the movie.
