Premise

A year after winning an Oscar for `The Miracle Worker,' Duke played Patty and Cathy Lane, `identical cousins all the way' (and received an Emmy nomination for the dual role). Patty was an extroverted Brooklyn Heights teen, while Cathy was a quieter, less impetuous and more cultured Scottish lass, living with her relatives until she finished school. Vastly different in every way, the cousins nevertheless made a good team for getting into (and out of) mischief.
