When Vancouver Social Services tell foster parents Joseph and Janice Hardy that they must install another bathroom in their old house - or lose two of their four foster children, the financial problem seems insoluble. A new bathroom would cost $10,000, which Mr. and Mrs. Hardy simply do not have. So will teenagers Nell, Billy and Tom, and nine-year-old Lisa, have to split up and leave the home and foster parents they have grown to love so much?

Then 14-year-old Billy has an idea: there is plenty of money in the local banks. Why don't they just rob a few of them? Before long Nell, Billy and a reluctant Tom, "The Three Musketeers", are following the example of Robin Hood: robbing the rich to help the poor.
