Riding uphill is hard -- but going down can send you over the edge!
Nancy, Bass, and George are all geared up for a bike tour in Ireland. They're looking forward to spectacular scenery, romantic ruins, local entertainment, and, at the end of the day, cozy inns to welcome them. But it isn't long before the three friends realize that they're riding with danger.
From the moment they arrive at the airport, someone seems to be targeting the tour members, especially the two teen sisters from Australia. Even worse, not all the cyclists are what they appear to be. As the group bikes along sheep-filled roads and steep seaside cliffs, the menace mounts. Nancy knows that if she makes one wrong turn she'll be on a detour to disaster!
