Blaumilch (Bomba Zur) is a patient in an asylum who manages to escape by sneaking onto a milk truck. He is dropped off in the middle of downtown Tel Aviv, where a road construction crew is busy making repairs. Blaumilch grabs a jackhammer and begins to dig a hole in the road. The police halt traffic, believing he is part of the road crew. The irate mayor demands an investigation and finds no one willing to admit that they were unaware of the hole-digging project. Through a series of bureaucratic bungles, departments clamor to receive credit for the unauthorized dig. Soon heavy equipment is called for to aid in the endeavor that everyone is afraid not to know about, as the hole becomes a canal that eventually reaches to the sea. When an official discovers the whole project is a mistake, he is hauled off to the asylum. Blaumilch, feeling his efforts have been overlooked, begins digging another hole in this satirical comedy.
