Mother and daughter are having a grand time living a ménage lifestyle
with stepfather. Everything seems to be going just fine. Until, that is,
when Father (Mother's first husband) returns from Japan to find
Mother's upbringing of his daughter has been an amoral influence, and
decides to obtain legal custody of his daughter.
Not having seen her father since she was a child, his daughter objects
(why break up a good thing at home?). She decides to 'lay' a trap for
her father. Posing as a girl out for a good time, she and her girlfriend
(for whom she has the hots) pick up her father and the ‘fun' begins. At
the last moment, they both leave Father ‘high and dry.' Not until
later, when they meet again, does Father realize that his unhappy
incident with the ‘fun girls' was in fact with his daughter whom he is
attempting to gain custody of. Knowing this, he decides his efforts are
futile for they are truly "Like Mother, Like Daughter".
