The film is a murder mystery set at the original Arsenal Stadium, Gillespie Road, Highbury, London, the then home of Arsenal Football Club, one of the dominant teams in English football. The backdrop is a friendly match between Arsenal and The Trojans, a fictitious amateur side. One of the Trojans' players drops dead during the match and when it is revealed he has been poisoned, suspicion falls on his teammates as well as his former mistress. Detective Inspector Slade is called in to solve the crime.[1]
The victim has been poisoned by a powerful digitalis-based chemical. There is evidence that he was being blackmailed.
The investigation gets complicated when the girlfriend (a prime suspect) is also murdered by the same method.
The police set a trap by putting a chemical on top of the poison, which turns the skin black after a few hours. The player responsible is then spotted whilst playing.
The film stars several Arsenal players and members of staff such as Cliff Bastin and Eddie Hapgood, although only manager George Allison has a speaking part. The Trojans' body doubles on the pitch were players from Brentford, filmed during the First Division fixture between the two sides on 6 May 1939; this was the last match of the 1938–39 season and Arsenal's last official league fixture before the outbreak of the Second World War.
Brentford’s players wore white shirts for the match because their first choice red and white stripes would have clashed with Arsenal's red and white jerseys. The Trojans’ players therefore wore similar white shirts in close up sequences which were then cut in with the match action.[1]
Dickinson planned a follow-up, The Denham Studio Mystery, which was intended to incorporate footage from the abortive film I Claudius, but this fell through.[5][1]
