Step into the strange and ultimately haunting world of Homer and Langley Collyer, New York's most infamous recluses. Born into wealth and privilege, the Collyer brothers withdrew from society, retreating into their house in Harlem filled with thousands of books, grand pianos, booby traps, and everything Langley could scavenge. Their bizarre lifestyle turned them into legends, but their story is also a cautionary tale about isolation, obsession, and the unintended consequences of shutting out the world.
