Jimson and Nosey seek shelter in an abandoned church. Jimson is immediately inspired to execute his largest work, "The Last Judgement", on a blank wall. Learning that the church is to be torn down within a fortnight, Jimson, Nosey and Coker recruit local youngsters to help complete the painting. A local council official overseeing the building's demolition objects to their activities. Jimson recruits Lady Beeder to participate. The painting is completed on the scheduled day of demolition. After the demolition crew warns everyone to stand back, Jimson suddenly drives a bulldozer through the wall, feeling it necessary to destroy the work before anyone else did. Jimson runs back to his boat and sets sail down the Thames before Nosey and Coker can stop him.
