O'Brien, for whatever reason, has been given the task of getting the goods on a sort of mafia syndicate. His engineering expertise is an asset to his role, but why he, of all people, would be given so much responsibility is beyond me. This job would require a skilled secret agent who could play the part of a trusted mobster. O'Brien is a shoot from the hip kind of guy and would probably be caught in a lie or slip up in the first five minutes. It's about a friendship that develops with a boss and the consequences of lying to him. Not a bad episode. Just not on a par with some others.
