The series follows a fictional training course for the Israeli intelligence agency the Mossad and focuses on the humane side of its agents and their personal experiences.
The series revolves around a secret Mossad compound called 'HaMidrasha', which is surrounded by surveillance cameras and is equipped with technological devices.
The compound operates a training course in which 13 trainees are sent to complicated missions in order to test their suitability for the occupation, and their improvisation, seduction and impersonation abilities.
He decides to create a new training program to test his trainees via unusual and radical situations, in which, apart from excellence, Yonna demands a creative "out of the box" thinking.
As individual trainees fail in different ways (physically, psychologically, ethically), they are unceremoniously dropped from the training program (and mostly from the show).
