When wealthy American expatriate Cornelia Wheelwright (Robson) is informed by her longtime lawyers that her late father swindled his partner, Fortune McCallister, out of $700,000, she acts decisively. First, because James Amory is the only lawyer in the firm to be outraged by the injustice, she hires him and fires the rest of the firm. His first task is to locate all of McCallister's heirs. It turns out there is only one: granddaughter Pam McCallister (Lane).
