A hero Andrey Obnorsky (Nikita Zverev), a young student-orientalist from Leningrad - along the line of the Soviet Defense Ministry falls on his Arabic language practice into Marxist South Yemen.

After being graduated from the Leningrad State University and urgent service of two years in one of the Soviet flying military schools - already as the interpreter/translator-officer Obnorsky goes again to the Arab World, now to Libya.

Finally, his friend Ilya Novoselov commits suicide leaving a very strange letter, and Obnorsky begins his own dangerous investigation which leads him to his old enemy from Adeni times his elder colleague and GRU man Kukarintsev (Pavel Novikov).

It was really a big and hard task to camouflage a routine lowest ranking serviceman-interpreter every day work and life with a war and detective plot full of danger and adventure making a readable novel for a wide Russian public of the mid-nineties.

However the film or series format demanded a return to some kind of remaking of true historical realities and to restore some general distinctive features of that time local environmental and cultural, political, ideological, military, social, native, conversational and many other exotic details, which are easy to be remembered and recognised by those who took part in that or similar events.
