The Tisza has meandered through the Great Plain for thousands of years. Ever since man first appeared on its banks, he has been trying to put the blonde river at his service. He has drunk its water, irrigated it, cut it up and levelled it. And 50 years ago he stopped it to turn it into a big reservoir.
 Little did he know then that his work would conjure up the world of the ancient Tisza. Thanks to the river’s waters, a unique ecosystem has been created. Man built it, nature built it. Thus was created a man-made paradise: the Tisza Lake.
 The narrator of the film, Dimitry Ljasuk, takes the viewer by the hand and shows, through all 4 seasons, what this special place has become over the decades. Millions of special birds and fish have settled here, and the dense vegetation has painted the banks of the blonde river green. Today, wild meanders, black-water inland lakes, labyrinths of reeds and thousands of islands are reminiscent of the ancient Tisza.
