The platoon travel to a secret location to be trained at a battle school. After a long train journey and a march in which they get hopelessly lost, they arrive late and end up missing two meals and the third is virtually inedible.

Starving and tired the platoon take on the assault course in which they try their best to get back at Mainwaring for getting them lost. The platoon then have to capture the 'enemy's camp' held by Captain Rodrigues and his men. This task looks impossible but can Mainwaring save the day and win back the respect of his troops?

Meanwhile Walker tries to raid the nearby farm to get food for his starving comrades.
