The consecutive absences of the Abbess from the monastery raise suspicions against Sister Arsinoe. The Abbess is forced to reveal her secret investigation and takes her along on the next mission. Sofianos and Tsakalakis use the findings from the forensic report and find out important information about Angelos' life. At the same time, Stamatis is afraid that the police will track them down and pressures Karaiskos to stop dealing with Petros' murder. A while later, one of the nuns is getting attacked inside the monastery.

After the explosion in the monastery of Agia Theodouli, nothing is the same. The nuns were saved, but Abbess and Sister Arsinoe are sure that they are now a target and the question is one, should they stop the investigations? At the same time, the police report speaks of an improvised bomb and the feud between Sofianos and Mytakos grows: are the nuns victims or perpetrators after all? Until the questions are answered, the sisters are taken to their new home, isolated and protected. However, they will not spend the first night alone. They will be somewhere very special, in the company of everyone involved in the story.

Abbess and Sister Arsinoe spend the night at the Pink Banana club and get involved in embarrassing situations.

But the day will end unexpectedly for everyone...

A threat from the past terrifies Abbess Maria, causing her to flee into the night and disappear. Sister Arsinoe is in despair, as -on the one hand- she searches in vain for the abbess and on the other she is called to save Chrysovalanto from Karaiskos who has kidnapped her.
