These are the adventures of 14-year old Kyle, his 12-year-old sister Teresa, and her friend Sonja, a beautiful Indian girl. Their fathers designed and built a time capsule unlike anything ever seen before. The children accidentally enter the machine and embark on an adventure into the prehistoric past.
