The freakishly over-organised Christine is now deputy leader of the Mid-Bucks Walking Club. Bob thinks he can handle this threat to his authority, saying: "She's Amanda Holden, she's Nick Clegg, she's the white-haired woman who used to sit next to Alan Sugar. We all know where the power really lies." But soon Christine is winning the hearts and minds of the group; especially Bob's best friend, Tom.

Meanwhile, stressed businesswoman Sophie makes a desperate leap on Victor, the 17-year-old geek. It's very important that her husband, Joe, doesn't find out about this or Victor may never see 18. Bob's daughter, Hazel, must help him cover it up by any means necessary.

On top of all this, the group must face down the rambler's worst enemy; a farmer who keeps blocking public rights of way. Will this make allies of Bob and Christine, or will it all end up in a big fight in a field? With the unpredictable Tom around, either - or both - might happen.
