In flashback from a ‘Rebecca’-style beginning: Ellen Foster, visiting her aunt on the California coast, meets neighbor Jeff Cohalan and his ultramodern clifftop house. Ellen is strongly attracted to Jeff, who’s being plagued by unexplainable accidents, major and minor. Bad luck, persecution…or paranoia? Warned that Jeff could be dangerous, Ellen fears that he’s in danger, as the menacing atmosphere darkens.

The series follows the mystery-solving adventures of the Teen Angels—Brenda, Dee Dee and Taffy—and their friend Captain Caveman (or Cavey for short), a prehistoric caveman and superhero whom the girls discovered and thawed from a block of ice.

Agatha has fond memories of her romance with college president Dr. James Merrill, when she was a student and he was her professor, and wants to see if there is still a spark between them.
