Most episodes focus on the mismatched pair driving around in a custom van, helping people in need along the way, similar to the contemporary NBC television series, The A-Team.
Escaping with a minor wound, McAllister finds himself in the small town of Ellerston, where he believes his daughter resides.
She is constantly on the move, and has been spotted in New Orleans (about six months to a year before she contacted her father; she was already using his surname at the time) Ellerston, Atlanta, and New York - working briefly but very successfully as a fashion model in the last city.
Teri herself is only seen in photographs: she appears as a strikingly attractive woman, somewhere in her mid or early twenties (despite dialogue in "Fat Tuesday" indicating her to be 28 or 29), with dark blue eyes and heavy black hair.
She is the result of a two-month affair between McAllister and a woman called Laura Kennedy, at the end of the Korean War.
Most information about her comes from "Fat Tuesday" and "The Good, the Bad, and the Priceless", both stories about women who know her vaguely and use her name to trap a villain.
However, the old master refuses to kill his opponent, preferring to renounce his ninja ways, allowing Okasa to make further attempts in future episodes.
[citation needed] For instance, most of the series (save for the first two episodes) have the heroes using shurikens for a variety of nonlethal tasks-throwing them to disarm an enemy, or using them as hand-held knives to cut through window latches-rather than the more stereotypical and lethal uses of popular mythology.
One succeeds to the headship of a House, by killing the current Master and taking his medallion (this is Okasa's objective throughout the series), but there are presumably less violent methods of succession as well.
McAllister's tendency to end duels prematurely by feigning injury or luring adversaries to charge through windows or into dangerous electrical equipment always takes his duelling partners by surprise, implying that his methods are not entirely "honorable" by their standards.
It is implied that the ninja are reverting to this darker and older tradition as of the series' time frame, and this may have been a factor in McAllister's departure from the "sect".
The entire, unedited series was released on DVD and Blu-ray by Kino Lorber under license from CBS Home Entertainment on February 20, 2018.
