After Buck comes in late after a night out on the town, Leslie becomes convinced Buck has a drinking problem and recruits the rest of the staff for an intervention. But while Buck did have a few drinks the night before, his real problem isn't alcohol. It's the person with whom he was drinking and the importance of keeping that person's identity from Leslie. When the secret finally comes out, Leslie reacts by suddenly considering himself "too old and alone." And it's up to Buck to mend the wounds to raise the boss' spirits with a night on the town and a very surprising encounter.
