The film "Spur der Steine" ("Trace of Stones") is showing at 4 and 7:30 p.m. Foreman Balla (Manfred Krug) is the swaggering, self-proclaimed king of a massive construction site in this East German drama, originally banned for its perceived anti-Establishment message. When a new Party Secretary is sent in to bring the site under control, along with a beautiful young engineer named Kati, a love triangle ensues.
