Contract on the Hitman

"The first rule of assassination: kill the assassins."

- Star Trek VI the Undiscovered Country

A professional killer (most likely a Hitman with a Heart) suddenly finds himself being hunted by the very organization he works for. Cue a plot line involving him taking out other assassins as he works his way through the ranks trying to find out who wants him dead and why.

Sometimes it's because the assassin wants to quit their profession, leading to The Syndicate (or The Government, or whatever other employers he's working for) reminding him, in deadly fashion, that there's only one way to leave. Sometimes it's because his employers don't want to pay him for a crucial job or consider him to have outlived his usefulness or failed them in some manner, particularly if he refused to do a hit for them that the assassin considered to be against his principles (women and kids are an all time favorite, falling In Love with the Mark being especially common). Sometimes it's revenge for a past loss or embarrassment at the assassin's hands, or because he or she wants something (or someone) that the assassin has and wants him or her out of the way. But most often, the reason for the Contract on the Hitman is because the employer doesn't want anything linking the killing that the assassin did back to them, and wants the assassin eliminated because -- say it with us, people -- He Knows Too Much.

Actually, they end up fighting against other government eployes almost as often as against actual terrorists or criminals.

Film
""In the first years of the 21st century, a third World War broke out. Those of us who survived knew mankind could never survive a fourth; that our own volatile natures could simply no longer be risked.

 * Handled more subtly in Mr. and Mrs. Smith; the two assassin organizations found out their best employees were married to someone on the other side, decided this was bad for business, and set them on a collision course so that they'd have to kill each other. The result is alternatively tense (as a straight up action thriller) and wryly amusing (as a metaphor for a troubled marriage).

Literature

 * Vlad Taltos in Steven Brust's Taltos series finds himself in this situation after a few books in the series.
 * The David Morrell (creator of Rambo) novels The Brotherhood of the Rose and Fraternity of the Stone, both involving US government hitmen. In the first novel the assassin kills a friend of the President in what he assumes is a CIA-sanctioned killing, but it turns out his controller is meddling in politics -- in order to protect himself the assassin is framed as a double-agent and slated for termination. In Fraternity of the Stone the killer has a mental breakdown when he sees he's orphaned a young boy in a bombing (the same thing happened to him) and so doesn't do the second hit on his list, angering his employers who needed the two killings to happen close together.

 * In The Assassination Bureau, Ltd., as in the movie (above), the Bureau's head willingly accepted a contract to have his group hunt him down and kill him. In the book, however, it wasn't to weed out unworthy members, but because the Bureau targeted people who harmed humanity and society as a whole. He'd been persuaded that by founding the Bureau, he had done harm -- since society wouldn't formalize true justice as long as there was already an unofficial means (the Bureau) of destroying evildoers.

Live Action TV
"This is getting ridiculous. The first assassin kills the second assassin, sent to kill the first assassin, who didn't assassinate anyone until we hired the second assassin to assassinate the first assassin."

 * Someone intended to assassinate the Buddha by sending one guy after him; then to remove the assassin by hiring two hitmen to wipe him out, then two each for those guys, then two more for those guys. He must have reckoned that by the time it got to the fourth level, none of the surviving ones would know anything about the first assassin's mission.
 * A similar legend to the above is told about the Greek tyrant and sage Periander. In his case, the first target was himself - he wanted to save his grave from being desecrated.

 * Outerlight's games The Ship and Bloody Good Time are based around this trope.

Don't fulfill your character's needs? You lose control and present your killer with a very vulnerable target.
