Wanda Saknussemm (Kathy Ireland) is a nerdy social misfit with large glasses and a squeaky voice who lives in Los Angeles and works at a diner. After being dumped by her boyfriend for "not having a sense of adventure", Wanda is informed via letter that her father, an archaeologist, has died. She flies to northern Africa and while going through her father's belongings, she finds his notes about Atlantis, apparently an alien ship that crashed millennia ago and sank into the center of the Earth. Wanda comes across a chamber beneath her father's apartment and accidentally sets off a chain of events that ultimately cause her to fall into a deep hole.
