Scottish barrister Sinclair McBride can face the most sinister criminals in London—but the widower's two unruly children are a different matter. Little Caitlin and Andrew go through a governess a week, sending the ladies fleeing in tears. There is, however, one woman in town who can hold her own.
Roberta "Bertie” Frasier enters Sinclair's life by stealing his watch—and then stealing a kiss. Intrigued by the handsome highlander, Bertie winds up saving his children from a dangerous situation and returning them to their father. Impressed with how they listen to her, Sinclair asks the lively beauty to be their governess, never guessing that the uncoventional lady will teach him a lesson or two in love.
