The poor relations are once again scrounging around for a plan for solvency. This time it is Colonel Sandhurst to the rescue. After happening on Sir Randolph's lovely daughter Frederica, the Colonel devises a plan to force Sir Randolph to settle his bill and to save Frederica from her fate.

Eliza Budley is a beautiful widow whose husband gambled away his fortune. Then Sir Philip comes up with a plan. He has heard that the elderly Marquess of Peterhouse is senile, a widower, extremely rich, and unlikely to remember whether Mrs. Budley is a relative or not. So off gentle Mrs. Budley goes to the bleak castle, where the marquess turns out to be not so old, hardly senile, and, in fact, quite handsome.
