Pink is a depressed rock star. He imagines a crowd of fans entering one of his concerts, and a flashback on his life up to that point begins. In the flashback, it is revealed that his father was killed defending the Anzio bridgehead during World War II, in Pink's infancy ("In the Flesh?"). Pink's mother raises him alone ("The Thin Ice"), and with the death of his father, Pink starts to build a metaphorical wall around himself ("Another Brick in the Wall, Part 1").
