She meets surgeon Daniel Warner-Bond, firstly in the boardroom of his father's company, but then in hospital where he operates on her sister. After a whirlwind courtship they become engaged, but there is a nagging doubt in Kayleigh's mind - Daniel seems unable to accept her commitment to the environment. She breaks off the engagement and takes a job in America, but realising her mistake she soon returns - to find angry protesters outside the company and Daniel engaged to his childhood friend Fiona!
