As the action moves to 1990, Jack decides to sell the flat, so Orla organises a final get-together for the friends. Victor is the last to arrive, bringing with him a revelation that stirs up old ghosts and secrets from the past - but that proves to be only the beginning in an evening of shocking confessions and angry truths. Finally, back in 2012, the sixth flatmate arrives to help - and it is clear that the consequences of that day 22 years earlier still haunt them. Claire Foy, Sam Claflin, MyAnna Buring and Lee Ingleby star.
