Deep within Buenos Aires's labyrinthine subway system, a train mysteriously disappears along with its 30 passengers. The subway officials are greatly troubled and call in topographer Daniel Pratt to help them find it. Unfortunately, the tunnels are so vast and complex, that Pratt needs his mentor Hugo Mistein to help him. Unfortunately, he too has vanished.
