In 1962 England, a young couple finds their idyllic romance colliding with issues of sexual freedom and societal pressure, leading to an awkward and fateful wedding night.

1975: A 200-ton blue whale gets washed up on a local beach and the kids think it’s the biggest thing that’s ever happened in Australia. Behind closed doors, the Mums and Dads of a quiet suburban street are going to celebrate in their own special way, by joining the sexual revolution and throwing a wife-swapping key party. And like the rotting whale, it’s all about to go spectacularly wrong.
