Brotherhood of the Rose (1989)

Romulus and Remus are two CIA agents, their direct instructor is John Elliott. They both were picked up at an orphanage by Elliott at the age of about eight, raised together as brothers and specially trained to supersede every other agent in the service. This is what they know. What they do not know is that they are part of a system Elliott had invented to build up his own private army of pros which can be assigned to any job he wishes.
