Witkacy under the tent, or "Crazy Locomotive" at the STU Theater, staged by Krzysztof Jasinski. The first Polish musical based on Witkacy's texts, directed by Krzysztof Jasinski. The beautiful and frantic music of Marek Grechuta and Jan Kanty Pawluśkiewicz, performed by the STU Theater orchestra, enchanted not only the audience, but also the actors themselves. The performance took place in a tent on Rydla Street in Cracow. The documentary shows the immense amount of work that the actors, musicians, writers and director had to put into preparing this astonishing performance.
