Synopsis:
Clark and Lana join Professor Lang on a trip to Tibet. When Clark saves the life of a lama, he is given a magic necklace that is said to protect the wearer from harm. Though believed to be a superstition, the power of the amulet seems to work when Clark proves to be invulnerable.

Later, Lana steals the necklace from Clark and ventures into the jungle alone. Superboy follows her and plans to secretly use his powers to protect her. However, it seems as if the amulet actually works.

Wilkes, Lang's guide, then steals the necklace. Superboy secretly captures him and gets the man to reveal that the amulet is a fake. He staged the dangers around Lana. Superboy then uses a trick to explain Clark's invulernability.
