Twelve-year-old Adam Murphy didn’t know anyone who had died, nor did his best friend, Nate Delaney. While testing new speedometers on their Malvern Star bikes, that changed – the pair witnessed beautiful Holly Castle, 16, hitch a ride to Sydney seeking fame and was never seen again. Presumed dead.

Twenty years later, Adam’s model mother, the IT Girl Winsome Keeley, gets hitched to the nation’s favourite singer, Jack Bernham, and the official photographer—Eric Castle—recognises Nate from their school years. The younger brother of the missing girl is still pursuing his sister’s cold case.

Adam and Nate are invited to take a ride.
