Price taught himself the basics of evolutionary genetics and formulated an equation widely acknowledged as the mathematical explanation for the evolution of altruism – something science had been trying to do since Darwin. The Price Equation was so extraordinary, University College London gave Price an honorary position within ninety minutes of him walking in off the street. The magnitude of his discovery shook Price’s atheism to the core. He believed it must be a gift from God. Three years later, Price was discovered in a squat having slit his throat. Seven men attended his funeral – five homeless and two of our greatest evolutionary biologists. This striking new work, directed by award-winning Director Laura Farnworth, shares the man, his work and extraordinary life. Watching Price wrestle with and ultimately falling victim to his theory, will have profound implications for the way we understand ourselves. Undercurrent weighs up the question: was Price mentally ill, or consumed by a spiritual desire to disprove his own theory: that man is only kind to his own kin? Price’s radical acts of altruism challenge us to examine our own acts of kindness in a time of austerity and self interest.
