When they're given up by their Aunt Goldie for custody in favor of their estranged grandfather, Anne can't help but think the worst of both adults. Once they arrive at the villa and are given a courtesy tour of the area, he shows them his most valued possessions over the years - among them an old motorcycle that's kept in pristine condition which the trio take a shine to.  Of course, Andy gets dragged into the world of motor racing by both Anne and Allan to prove their bullies wrong, and only the bike could save them from getting into deeper trouble than they already are. Can Anne and her brothers keep it a secret among themselves? And how does the old man not suspect anything?
