A posting to Germany hasn't quite lived up to the excitement levels of Afghanistan and Iraq and Gary is desperate to get home. But when Charlie announces that he's just got engaged, the final week gets a lot more interesting.

Gary's initial misgivings are replaced with his excitement at being asked to be best man, and he starts making preparations for his special day.
