Kitty Charing's life-changing inheritance comes with a catch.
Her eccentric and childless guardian, Mr. Penicuik, is leaving Kitty all of his vast fortune - but with one condition. She must marry one of his five grand-nephews.
However, Kitty's clear favourite - the rakish Jack Westruther - doesn't appear at all interested in the arrangement. To make Jack jealous, Kitty impulsively convinces his cousin, the kind-hearted and chivalrous Freddy Standen, to enter into a pretend engagement.
But the more time she spends with Freddy, the more Kitty wonders whether Jack is the right choice after all...
