Synopsis for my film

My film is a gangster action fusion. My opening scene will combine both of these genres clearly.The synopsis for my film is:A gangster requires help from a small time assasin on a crucial job. At first the job appears simple, get to the location on time, kill the guards get the brief case and go. But the deeper the assasin gets the more he realises that this isn't an every day job. It seems that this not only involves every major crime family in the country, but the police and even the government. As time runs out for him to figure out the reason he was chosen for this suicide mission he must decide...kill or be killed
