"Black Widow Strikes Again"
Black Widow returns to Gotham City, using a hypnotizing device to convince bank managers to give her thousands of dollars. Batman soon realizes that she is making her way through the city's banks in alphabetical order. After seeing through her disguised hideout, they enter to investigate and a fight ensues.
Batman and Robin track Black Widow to a house in the suburbs, but are fooled by her robot senior citizens rocking on the porch.
