In his homemade show Limmy, aka Brian Limond, opens the door to a tradesman who gets more than he bargained for and to a group of young men whose dabblings in the spirit world prove unsettling. There's also the appearance of a mysterious individual during a routine piece of filming at home. A visit to the museum prompts a vision of the future and while meandering by the river, Limmy attempts an academic explanation of how comedy works to a tough audience. Meanwhile a walk in the park which he takes to improve his health goes down a strange route after he recalls a previous encounter with a litterbug.
