Gary takes part in a debate about the Iraq War in University of St Andrews against an anti-war student, organised by the OC's annoying brother.

Following a prank that went wrong, Sergeant Thomson takes a brief break from his day off to punish Gary and the boys by putting them on kitchen duty for the Captain's important dinner. Chef works hard to keep them under control while also trying to create a dinner good enough to impress Colonel Fanshaw, the Captain's father. But when an inebriated Thomson returns to wreak havoc in the kitchen, it's left to Gary to ensure that the dinner is a success and the Captain isn't embarrassed in front of 'Colonel Daddy'.

Gary delights Captain Fanshaw by 'saving his life' on a competitive skills exercise. With the enemy being led by his father, Colonel Fanshaw, the Captain is so grateful that while the others are fending off the Colonel's increasingly audacious attacks, he offers Gary a new job that sounds too good to be true - and turns out to be exactly that.
