Thirty miles outside Johannesburg, a group of school friends decide to spend the night in a network of underground caves. The area is known as the Cradle of Humankind. The oldest pre-human remains have been found there, including a four million year-old ape-man called Little Foot. As the friends go deeper underground, forces are unleashed between them and around them. Part reality, part nightmare, South African playwright Craig Higginson's dark and poetic play takes us on an unforgettable journey into our unconscious ancestral memory.
