When Ben's adoptive parents move to the Middle East temporarily, he is left to care for his younger sister, Caitlin. Ben struggles to act in the role of guardian as Caitlin finds it difficult to settle in and is used to having things done for her, as opposed to living in a share house environment. Ben takes his interest in motor racing for the next level and begins spending more and more time at the race track. Lou offers his support but Ben finds it difficult to be competitive, even when goaded by rival racer Steve Van Eck (Daniel Tobias). After Barry Sheene has a few words of encouragement to Ben, he gets the motivation he needs.
