Adrijana (Jokovic), daughter of a Serbian teacher (Samardzic), falls for Miljaim (Trifunovic), believing him to be a dashing Italian businessman. At first their life together is happy, but as Miljaim makes them move around all the time, Adrijana eventually demands an explanation. Miljaim gives in and starts speaking Serbian, explaining who he actually is: a professional assassin. But their love is too strong to end over this, and they stay together. Soon, however, the young couple must face the consequences of their love. The title Strsljen (Serbian for "Hornet") comes from Miljaim's assassin name. Ironically, Miljaim's brother Abaz (Popovic) happens to be a high-ranking police officer who's trying to find out the identity of the feared Hornet and catch him before he can commit a politically-based murder in Kosovo and possibly trigger a new conflict.
