A.R. Rawlinson writes and produces this 1950s British thriller starring Philip Friend, Mary Mackenzie and Leslie Dwyer. The film follows former lovers Kyra Gerbaine and Felix Gretton (Mackenzie and Philip Friend) as they are reunited in a London hotel, years after separating during the war. Their relationship had previously compromised Felix's post as an intelligence officer and allowed a spy to escape. Now working as a waiter, Felix sets out to capture the spy by employing Inspector Fred Borcombe (Dwyer) to track him down after Kyra spots him in the hotel.
