In Paris a leading theatre impresario is murdered on opening night, shortly after replacing his leading lady. A police Inspector in the audience takes over the investigation. The film was shot at Elstree Studios. It was a close remake of the 1937 Austrian film Premiere and re-used a number of musical scenes from the original which were dubbed into English.
