Swordfish

Stanley Jobson (Hugh Jackman) is a computer hacker that infected the FBI's Carnivore program with a computer virus. His parole forbids use of computers and the internet. His alcoholic ex-wife Melissa married a rich porn producer and is a part-time porn actress. She has a restraining order against Stanley, the father of their daughter Holly. Ginger Knowles (Halle Berry) persuades him to work for Gabriel Shear (John Travolta), who has a gun held to Jobson's head giving him a minute to crack a secure government server. Gabriel offers Jobson $100 million to program a multi-headed worm, a "hydra", to siphon $9.5 billion from government slush funds.
