S9E5. Bald, Bold & Bagged

Ok, so there's one giant bag and inside that bag there are 9 sub-bags. Each of these 9 sub-bags, apart from bag 9, has other smaller bags inside them - think of them as sub-sub-bags.

Oh, and these bags are filled with people and each bag, including sub-bags and maybe sub-sub-bags, are in competition with each other.

What are the bags and their many many sub-bags fighting for?

Have a listen and find out.
