Domestique(2018)

Roman is a top level cyclist recovering from an injury through hard work and strict regimen. To improve his performance, he even sleeps in an oxygen tent installed in his bedroom. That is a bitter pill to swallow for his wife, Šarlota, whose long-time wish is to conceive a child. And so they both brim with determination, get lost in their obsessions, and improve their bodies to a point where they might even frighten themselves.
