Widower Sir Michael Stewart is stunned when he learns that his elderly neighbor has left her cousin, the forthright but lovely Catriona Grant, to him in her will.

But when his married daughters in London hear gossip about the interloper they rush home to keep the two apart. Eventually though an even greater surprise emerges when Catriona turns out to be more than just an anonymous poor relation.
