Based on the short story "Sept petites croix dans un carnet" by Georges Simenon. "Sette piccole croci" was the first drama, non-series (what is today called a TV movie), as well as the first police thriller to be broadcast on Italian television. The story follows a tense cat-and-mouse chase across Paris on Christmas Eve.
