Plot Synopsis

These special compilation episodes of UNXPLAINED explore the world's most fascinating, strange and inexplicable mysteries. In series opener, "Mystical Structures," for thousands of years, people have held the belief that everyday objects can possess hidden energy. Talismans are seen as providing protection, good fortune, and some are even thought to embody a higher power. Could it be that what fuels our faith in talismans is not superstition, but a real connection to something beyond our world?
