One of the film stories based on the old Prague legends. This one is about the old master clock maker Hanus who construed the Prague Old Town astronomical clock. Master Hanus' clock started working for the first time in 1490 but did not tell the time for too long. Soon the master, blinded by the perfidious town councilors, stopped it for more than 200 years.
