It is Cassie Bennett's last day at Mapledale School for Girls, one of the most exclusive schools in England, but there is one thing she wants before leaving - and while she has the opportunity.
Mr. Knight.
The elusively handsome headteacher's strong physique and devastating looks have haunted her for years, and now the normally timid Cassie is determined to have her wicked way with him or forget him forever. But what was intended to be a quick fling soon turns into something darker, dangerous, more addictive and more enticing.
In the headteacher's office, the tables are quickly turned and Cassie discovers an intriguing side to herself that she never knew existed. The commanding and sensual Mr. Knight draws her into a private lesson that she'll never forget. But will Cassie be a good pupil or will Mr. Knight be forced to discipline her?
