Police Inspector Mayne (Patrick Jordan) is also after those plates and keeping Don under surveillance. Don is desperately trying to find the plates, and the identity of who is after them before his daughter is snatched. When Don's photographer friend Chas (Brian Nissen) is found murdered then Don also has to deal with being hunted as the prime suspect...
Kay also has to deal with his slimy landlord boss Benson (Arthur Lovegrove). Its a bit cheap but that adds to the grittiness of early 1960s London. Not a fantastic film but perfectly serviceable.
