Martino has some awkward conversation with Sally. Meanwhile, word about Martino's disappearance has spread all over Italy, and as a result, the TV show Missing has come to town.

The investigation gets going. Luca, officially still off duty, had just come to meet his sister at the bus, but naturally, he can't help getting involved in the case, which causes a bit of confusion on the team. Rosmini comes to examine the victim.

Peppino and Martino watch the TV show, and as Martino's story unfolds, Peppino has pretty much taken center stage and is basking in it. During the interview, he says things Martino is not thrilled about, to say the least.

Tiziana is confused because she has no clue that she might be a suspect. Raimondi, who shows up with Rivera, is confused because he doesn't realize Tiziana is Luca's sister. Poor Tiziana!

Martino, Sally, and Peppino are watching the TV show Missing, where there is some news about where Martino might have been sighted. A very special appeal is made that's very disconcerting for Martino. Peppino is philosophical about the whole thing.

Manara, and Raimondi meet with their chief, Casadio to discuss the case and Manara's status, but the meeting has an unexpected outcome. Meanwhile, the only real suspect is Luca's sister!

While Martino plays his guitar for Sally, Peppino figures out that three's a crowd and leaves. Ginosa has become a bustling tourist town, and Peppino is back at work as a "tourguide."

Manara is back in the saddle. Raimondi leaves for Rome after a frank conversation with Luca, and another one with Marta. Quattroni has some important information weighing on him, and goes to talk to Manara.

A famous TV personality arrives in Ginosa and wants to talk to Peppino of all people. She thinks she has him figured out.

During questioning, the passengers seem to agree about one person getting back on the bus during the rest stop: Luca's sister. Buttafuoco and Barbagallo finish up checking the luggage, but they come across an extra bag.

Peppino brings Martino some magazines singing his praises. But the two friends don't agree on what should happen next, and things get unpleasant.

The contents of the blue backpack point to a possible motive. Luca talks to his sister again, but she is still visibly upset, which is understandable. Marta finally talks to Luca about what has been weighing on her for a while.

Martino makes an important decision, but gets stopped in his tracks. He's going to have to change his plans.

Luca goes to see Ginevra about the autopsy, but he confides in her, too. Toscani is having trouble telling Luca the results of his investigation into the passengers of the bus.

Martino has a hard time accepting what the priest and police have come to tell him. He's stuck.
