It's late and in the backyard of a harbourside mansion, the remains of a great night litter the lawn. Nathan is heading off for a new job in Shanghai, his grandma Marg has thrown him a farewell party and his mum Stephanie has arrived back from book club armed with his favourite dessert. Beyond the manicured hedges and sandstone hedges sit press trucks and photographers waiting to capture a newly minted celebrity. Nathan’s legal team, having deployed especially vicious tactics, have won a precedent setting and publicly deplored acquittal. With their world on the precipice Nathan is keen to move on, Marg wants to point the finger of blame anywhere but her grandson and Stephanie desperately tries to contain her opinions over the matter. When Marg makes the radical suggestion that Nathan stay in Sydney and face the music, the fragile family peace begins to swiftly unravel. Set over the course of a single evening and diving headfirst into the aftermath of the #metoo moment, Leviathan asks what responsibility communities have for the actions of individuals and how much damage can a family sustain before bursting into flames.
