The episode premiered to Nielsen ratings of 4.6, which is about 4.5 million viewers. Plot O'Brien is sent to infiltrate the Orion Syndicate on an out-of-the-way planet called Farius Prime. Starfleet Intelligence has given him the cover of a "fix-it man" down on his luck, knowing that the Syndicate is recruiting people with such skills. He spends his days in a bar frequented by Bilby, a local Syndicate operator. O'Brien creates an opportunity and makes the most of it: when one of Bilby's men, Krole, is attempting to hack into a computer belonging to a local restaurant, O'Brien sabotages the computer to damage Krole's expensive hacking equipment. Miles saves Krole from injury, introducing himself as "Connolly", and volunteers to fix the equipment. Later, O'Brien repairs three broken Klingon-made disruptor weapons for Bilby, thereby winning his trust. Bilby "witnesses" for O'Brien before his boss, Raimus, taking responsibility should anything go wrong with "Connolly"'s involvement in the Syndicate.
