A group of scientists in search of lost Atlantis are plane wrecked on an uncharted island full of stock footage monsters fresh from One Million BC. Occasionally we get an original papier mache monster peaking out from behind an alcove, but for the most part this is typical Mexican filmmaking for the period. With Armond Silvestre and Alma Delia Fuentes.
