Lara keeps her promise to the doctor, but in the process falls victim to some gossip among her colleagues at headquarters.

A pleasant evening at the circus gets interrupted when Lara gets a phone call and rushes off to the hospital.

Let the show begin! We're at the circus, and the ringmaster looks familiar to one of the women in the audience. Meanwhile, Manara has un unexpected encounter as he leaves the nightspot.
