When jeweller Fahrettin Muftugolu is found dead in his apartment in the Istanbul district of Vefa, it looks like suicide. Searching the jeweller's home, Inspector Mehmet Suleyman and his team come across a hoard of extraordinary artefacts including solid gold religious relics and a mummified human head. But are they real and, if so, who owns these priceless possessions?

As his colleagues begin their investigation, Suleyman is distracted by troubles of his own. His wedding to Gonca Serekoglu is days away, but when Gonca receives her bridal bedcover from a Roma haberdasher and discovers that it is covered in blood, she sees this as a curse on their marriage. Suleyman asks his old friend Cetin Ikmen to help him uncover the truth, but the task is not that simple...

Meanwhile, as the stories swirling around Muftugolu become increasingly sinister, the dead man's wife appears, laying claim to his valuables, and Suleyman is drawn into a dark and dangerous world of smuggling and savagery . . .
