Dagger Eyes

The German and Pamela are mysteriously killed in rapid succession and Mystère is saved from an aggression only by the prompt intervention of Inspector Colt.

The German was in fact a photographer who had taken very compromising shots of an attack by the Soviet secret services on an American office in Piazza di Spagna where a politician was assassinated.

Colt then kills his boss and decides to deal directly with the secret services to be able to obtain a large sum for the film and escape to make a new life with Mystère.

Mystère finds Colt in his golden exile in Hong Kong and instead of taking revenge, the couple fall in love.

[4] Roberto Curti stated the film had "good commercial results" leading to the Vanzina brothers to develop Nothing Underneath.
