Mulder believes metallic objects discovered on the coast of West Africa are proof of the extraterrestrial origin of life on Earth. He falls mentally ill under the apparent influence of the artifact while Scully goes to Africa for answers.
An artifact with strange engravings on it is found off of the coast of Africa. When a rubbing of these engravings is shown to Mulder, confusing noises happen inside his head. The agents look to uncover the origin of this mysterious artifact and to find out why it is having a singular effect on Mulder.—Muldernscully
