The third season of the television series HaShminiya was originally broadcast on Arutz HaYeladim (HOT) in Israel.
When a weird guest is coming to the villa, everybody in the octette, except Aya, joins the police's secret organization "HaMoatza".
Aya prefers to spend her summer holidays helping pregnant Dganit and reading books.
The octette introduce themselves to Alex, Lillie's sister and the head of "HaMoatza", and the three procurators, Yoel, Dafi, the weird guest, and Omri.
At the same time, Avi, who becomes the Shminiya commander, breaks up with Mika and moves into Czechov's place, a member of "HaMoatza" too, and an old friend.
