A celebrated film director (played by Lior Ashkenazi) recounts his unconventional efforts to complete a film abandoned in the wake of the 2022 Russian invasion of Ukraine. Meanwhile, fragments of that abandoned film imagine avant-garde composer Alexander Mosolov's purging in 1930s Stalinist USSR and efforts to smuggle his music (reported lost in a stolen suitcase) into the West. Inspired by filmmaker Matthew Mishory's own doomed efforts to make a film in Moscow about the titular composer, Mosolov's Suitcase is a black comedy about the imaginative possibilities of cinema and the human quest for freedom.—Monolithic Films
