Bells from the Deep (1993)

A band of seekers rests on the fragile ice of Lake Svetloyar, embarking on a quest to find the fabled city of Kitesh. Legend has it that the city was spared from the invading forces of the Mongolian prince Batyi when God allowed it to submerge beneath the lake's surface. Those who listen closely claim they can hear the bells of Kitesh's cathedral ringing from the depths below.
