Chrissy Grieves is good at her job at McGregor's Transport, and works hard - which leaves her little time for relationships. Besides, she's been unlucky in love, and her mother hasn't exactly been the best role model in that department. So when the boss's son, Mark, is brought home to keep an eye on the business while his parents are on holiday, the last thing Chrissy expects is to fall for him - and she's determined to keep her distance. Can Mark persuade her to take a chance on love?
