The Jackal, the most dangerous hitman of the world, is supposed to avenge the death of a Russian gangster that died at the hand of the FBI. The FBI wants to prevent this assassination, but there is next to no information about the Jackal for them to go off of. It is even questionable if the Jackal exists at all. Desperate, the FBI turns to the Irish freedom fighter, Declan Mulqueen, who is incarcerated in a prison in the USA. If his release from prison is guaranteed, he wants to try whatever it takes to identify the Jackal. This marks the beginning of a race against the clock.
