Murder, betrayal, office politics, temptation... it's all in a day's work for Detective Salvo Montalbano. With his always loyal and sometimes effective police squad he solves crimes in Vigata, crossing paths with housewives and priests, liars, saints and Mafia dons. He also wages a personal war with his own demons, which fight against his professional ideals and personal commitment to beautiful long-distance girlfriend, Livia. Yet there's always time to indulge a long-standing flirtation with his ultimate temptress, Italian cuisine. The series is filmed in the ancient, sun-washed Sicilian city of Ragusa, and is based on the international best-selling mystery novels by Andrea Camilleri.

When a camera crew videotapes Montalbano and his men entering the home, they become overnight heroes.  The publicity brings out the kooks, however, and a disturbed maniac begins a macabre treasure hunt with Montalbano, sending him strange riddles linked to the kidnapping and murder of a young girl.   Montalbano and his team try to sort out the insanity before a new murder is committed. Episode 22 - The Age Of Doubt - Nothing is as it seems in Inspector Montalbano's investigation of a corpse found at sea.   When a young girl arrives from Palermo claiming to meet her aunt, who's pulling into Vigata harbor in a yacht, he  discovers a connection between the corpse, the yacht, and a motorboat called 'Ace of Hearts.' He finds himself attracted to a young Coast Guard officer assigned to help in the case, but there's no time for soul searching when a second corpse shows up and there's a gruesome mystery to solve.
