Held in Twinsburg, Ohio since 1976, the Twins Days Festival is billed as ‘the world’s largest annual gathering of twins’. Twins Days chronicles the weekend-long celebration, where twins of all ages and from all over come together for twice as much fun. Surveying attendees on their extraordinary connections and the benefits and drawbacks of having a near-identical companion, the US director Alex Markman provides a playful yet insightful look at the psychology and experience of twinned life.
