Struggling artist Brindsley Miller and his fiancée Carol are having a party with the aim of impressing Carol’s bombastic father, Colonel Melkett, and millionaire Georg Bamberger, who may buy some of Brindsley’s sculptures. They have borrowed (without permission) the furniture and effects of their fussy neighbor, Harold, to make the flat more presentable. Before the guests arrive the main fuse blows, plunging the flat into darkness; only we, the audience, can see what is happening. What follows is a frantic romp with unexpected visitors, mistaken identities, and surprises lurking in every dark corner! The result, as you might expect, is chaotic, disastrous – and very funny!
