Break of Dawn.

An ex-con suffering from terminal cancer and a suicidal ex-legionnaire are hired to participate in a staged assassination attempt on a Romanian politician. As part of the plan, the two must themselves be murdered in order to make their target appear more powerful. But while their circumstances make them perfect fall guys, their lives are initially spared when the attack descends into chaos. Staying alive thereafter involves the two strangers working together to dodge both fellow conspirators and the police.
