Matt Cook wrote the screenplay, which centers on a group of cops who are blackmailed by the Russian mafia to pull off an impossible heist. They realize that the only way to do so is by setting up a fellow officer to be killed, although their plan backfires when the rookie cop they set up to die foils their attack. The title refers to 999, the police code for "officer down."
