An impossible escape, a death-defying railroad ride, a crossing to a magical land. Five fugitives have nothing to lose but their chains. But the hounds of hell are hot on their tail. And the quest is yet to come.

Five performers, chained together on stage by iron manacles, are allowed no exits or entrances, no private moments, no secrets. The show features five-part harmony and acapella singing, in a range of styles, from doo-wop to barbershop to gospel and beyond.
