The story centres around Chris Rouse and his son Chrissy, whose diving careers spanned a mere four years, before they both died following a dive to a recently discovered U-Boat. They were aged thirty-nine and twenty-two respectively.
The highly committed and experienced pair of divers were singular in their generosity to others, and the constant bickering and taunting between themselves. They were knowledgeable and open to adopting new practices and technology to improve the safety margin on their dives. There appears to be no doubt however that they also enjoyed challenging limits, and were pressing ever further into cave and wreck diving.
