| A psychologist tracked down runaways in what began as a short-run series called `Operation: Runaway,' which aired in the spring of 1978. It was slated for a fall pickup, but was shelved until the following spring, when it had a new title and some new cast members, including Alan Feinstein, who replaced Robert Reed (four years removed from `The Brady Bunch'). |
