Chris Rodley documents the 50th anniversary of 'The Prisoner' (1967), the British television series starring Patrick McGoohan. Rodley reflects on his earlier film-making days and his attempt to interview McGoohan on the mysterious series. In 1983, Rodley looked to materialise his documentary 'Six Into One - The Prisoner File', intending to explore the ideas of 'The Prisoner' and its concepts. Unfortunately this did not align with Rodley's vision, and now over 30 years later, he accesses unused footage from McGoohan and interviews with his daughter, Catherine, to fulfil his curiosity around this cryptic television drama.
