About the title
A single mother has to work a great deal and has hardly any time left for raising her children. Meanwhile, her teenage son and young daughter, in search of entertainment, cause their mother no end of trouble, including unexpected expenses. One day, worn out by her children's hyperactivity, the mother decides to turn to their elderly neighbor, Miss Robinson, for help. The kids are not at all thrilled by the prospect of an old nanny appearing in their house, one who seems like a rather eccentric character. But it soon turns out that Miss Robinson is a legendary superhero with the secret codename Agent Fighter. And very soon the children find themselves swept up in a dizzying adventure, helping the battle-ready old lady save the world from an onslaught of villains.
