When race caller and television presenter Mark Shillingford calls a race in which his twin sister Clare, an accomplished jockey, comes in second when she could have won, he believes the worst: She deliberately lost, and the race was fixed. When Mark confronts Clare with his suspicions, she storms off. That is the last time Mark sees her alive. Clare jumps to her death from the balcony of a Londen hotel. Devastated and guilt-ridden over her death, Mark goes in search of answers. Why would Clare throw a race? Why would she take her own live? Order was it suïcide at all?
