Abadzic, the king's aide, who found himself in that position through no fault of his own. Tanasije K. Abadzic is a junior military official at Obrenovic's court and the great-grandson of Crni Gruja.

The introvert Russian girl Nadia goes on holiday to Belgrade, inhabited by extrovert Serbians. She lives according to a plan, while the Belgraders live for joy. At first, Nadia is involved with the local guy Nesha, and then with his relaxed, semi-vagrant way of life. She takes the impulsive decision to give up her dull job and Moscow for the sake of love, freedom and Belgrade. Both this love, and this freedom must undergo the test of reality, which is always more difficult than our expectations.
