In the stark isolation of a remote Australian lighthouse at the end of World War I, a woman finds herself shipwrecked by circumstance. Miranda Otto stars as Meredith, a shy and unmarried woman who arrives on South Solitary Island with her uncle, the new head keeper played by Barry Otto. The unforgiving landscape and the small, strained community of keepers and their families become her entire world, a place of howling winds and profound loneliness. Her quiet existence is disrupted by the island’s assistant keeper, the brooding and war-damaged Marton Csokas, whose trauma has made him a recluse. In this atmospheric drama directed by Shirley Barrett, the harsh elements outside mirror the emotional turmoil within as Meredith navigates unspoken tensions, the judgmental eyes of others like the keeper's wife Essie Davis, and a tentative, fragile connection that threatens to upend her guarded heart. A poignant story of isolation and the quiet yearning for human contact, South Solitary captures a time and place where survival depends as much on emotional resilience as it does on keeping the lamp lit.
