Angelos Epithemiou (played by Dan Renton Skinner), the regular guest panellist from BBC Two's Shooting Stars and erstwhile burger van owner, is given the opportunity to present his own show on Radio 4 as an experiment to get "new voices" onto the radio.

He has decided to examine the big issue of environment and invited two experts along to share their views - Kate Schofield, a spokesperson from Greenpeace; and Toadstool, an environmental activist.

Will Angelos be able to set the world to rights or will it end in meltdown?
