Koper (2006)

We're always searching without knowing what is lost.

Yahya, a low-class employee, finds a suitcase on an empty street. The suitcase is suspected to contain robbed money from a bank. This results in everybody giving the once invisible Yahya the royal treatment, with the hope to get a little reward in return. But Yahya is determined to keep the suitcase, until a series of events in his life prompt him to consider his decision.
