The official synopsis:
First day on the front line? Time to attach a Headcam for a soldier’s point-of-view. What could possibly go wrong?The minisode is currently only available through iTunes as a 'series only' feature. It was previously priced at £2.49 for UK fans but free to watch in the US, which was a mistake according to a Radio Times article. The Last Day will also be included as a special feature on the DVD / Blu-Ray release of the 50th anniversary adventure, and we will keep you updated if the clip is made available to watch online.
