The film is essentially a feature-length commercial for an exhibition to mark the 40th anniversary of the nationalisation of the Czechoslovak film industry, to be held at the Prague U Hybernu venue. The protagonists of the piece are comedians Oldrich Kaiser and Jirí Lábus, who are set to accept an award from Japanese television representatives at the exhibition. At the same time, five gangsters plot to seize a revolutionary invention devised by professor Suzuki - a super holograph, which enables any figure from television to be transported in the flesh into the real world, and vice-versa.
