Croatia. A holiday destination for hundreds of thousands of Czech and Slovak tourists, who come here for the sea, mountains, monuments, entertainment, and relaxation. Because even in a holiday paradise, sometimes things go wrong. And sometimes there's murder... The story of the series takes place on the island of Hvar, where a central pair of Czech-Slovak detectives helps to solve crimes involving Czech and Slovak tourists. Michal and Ivana are like fire and water. While he is a funny, sarcastic detective from the "old school," she is a free-spirited, temperamental woman. Together, they must restore the disrupted harmony of the sunny island. The mixed local police force gets to investigate even the most serious crimes. The rule is clear. A Czech body, a Czech chief investigator. And vice versa.
