Sam is doing a green school project and dares Dani and Toby to cut their carbon footprint. Can Toby survive without all his electronic gizmos? Max and Ben offer to offset some of his carbon as their latest moneymaking scheme. Do they know what they are letting themselves in for?

Dani and Max are snowed in alone! At each other's throats at the best of times, how will they possibly survive the claustrophobia of having to spend a whole day in each other's company? Also, there's no food and no heating. Who will trudge through the snow first to save the two from themselves - Sam, Toby or a very lost Ben?
