After spending time exploring the British love of water, Jo Brand performs a one-off comedy set reflecting on her experiences of Britain's lakes, rivers and seas.

Jo meets the RNLI as they train for a maritime emergency and joins Meera Syal in a raft race.

Jo meets a man who can hold his breath underwater for a staggering 20 minutes, and Rich Hall tries a traditional canal holiday.

Jo asks Bill Bailey to help her assess the trendy new craze of wild swimming, and also tackles the Olympic white water canoe slalom course.

Jo attempts synchronised diving and invites Sean Lock to join her in a very muddy race.
