Nick Rowan has been made acting Sergeant at Ashfordly. A girl, Tracy, gets involved with two bikers from the fair who perform the 'wheel of death'. Tracy's dad is depressed and her sister Belinda is seriously worried about him. Tracy's dad is seen threatening Dirk (one of the bikers) to leave his daughter alone. Consequently he becomes a suspect when oil is poured down the 'wheel of death' causing Dirk to fall. It turns out Tracy was responsible but she intended to harm his partner so she could join Dirk in his act. Trevor Lamus becomes the target of a hate campaign. Soap powder is put in his beer and a grave stone put up in his name. Nick asks Mike to investigate. He finds that most of the locals including Alf had all chipped in to buy the stone. Nick realises that its awkward and when Mike points out the paper work involved he lets them all go. But he wants a word with Alf about his involvement! (thetvdb.com)
