Rebecca depletes the blood supply while she and Bobby operate on a soldier with severe gunshot wounds, forcing Colonel Marks to call for a walking blood bank. Pedersen questions the soldier's buddies about the circumstances that lead to the shooting, but their stories don't add up. Simon rekindles a relationship with an old flame - an attractive photojournalist on assignment.

Reluctantly, she rises to the occasion and, with the team's help, orchestrates a shindig complete with Western theme, campfire, food, music, dancing and a mechanical bull. Vans discovers he has a knack for more than just translation.
