Flood

T1, E6: During heavy rains, London floods and the Young Ones are trapped in the house. When they embark on a game of hide-and-seek to pass the time, Mike finds a lion tamer in his bedroom and Vyvyan hides in a wardrobe and enters Narnia. But the sharks at the window and the arson attack on Rik's bedroom pale into insignificance when their landlord Jerzei Balowski turns into a homicidal, axe-wielding maniac.
