Publisher's summary
Mike Yates braves a stormy night in the Lakes to help celebrate a milestone for John Benton. An evening of fond reminiscences of old glories and friends awaits. But a long-buried past is about to catch up with them.

Meanwhile, on the rain-lashed moors, what begins as a routine mission for modern-day UNIT quickly becomes a fight for survival.

Plot
Benton is planning on moving abroad with Margery and holds a party at his pub in the Lake District with his friends from the British Army. Yates arrives late, after most people have left due to the weather, and is attacked by a drunk Terry who believes that he is to blame for him not entering into a relationship with Anne.

On the moors, UNIT soldiers fight against and evade Silurians, led by Grand Marshall Jastrok, to allow Kate and Osgood to escape. They reach the pub and explain to Yates and Benton that they were ensuring that the Silurians at the hibernation nest at Scafell remained safe and asleep when Osgood realised that the place was awake. Kate attempted to enter into dialogue with Jastrok, but he had his warriors attack and Captain Burmaster covered her and Osgood as they ran.
