Riotous and hilarious comedy. Four old friends sit down for a quiet evening together. But they are harassed by various bells, sirens, buzers, warblers, beepers and cheepers, all trying to warn them of something. What are these electronic voices so urgently trying to tell them? Can they understand the mysterious messages before disaster strikes? It's a race against time- because there are seven more plays and twenty more characters still to come before the evening is through, plus a lot more strange noises - and increasingly desperate calls from eleven separate pay-phones.
