Near Penn Station, next to the Amtrak tracks, squatters have been living for years. Marc Singer goes underground to live with them, and films this “family.” A dozen or so men and one woman talk about their lives: horrors of childhood, jail time, losing children, being coke-heads. They scavenge, they’ve built themselves sturdy one-room shacks; they have pets, cook, chat, argue, give each other haircuts. A bucket is their toilet. Leaky overhead pipes are a source of water for showers. They live in virtual darkness. During the filming, Amtrak gives a 30-day eviction notice.
