Petr (Matěj Hádek), a 30-year-old former professional cyclist, works as a bike courier in Brno. Non-conformist and irresponsible, he treats his job as a temporary stopgap while living in a leaky apartment with his student girlfriend, Šárka (Eva Leimbergerová), who bears the financial and emotional burden of his unpredictable behavior. Petr's carefree lifestyle abruptly collapses when he causes a severe accident involving his fellow courier friend Igor (Jiří Vyorálek). Confronted by the consequences of his actions and forced to re-examine his selfishness, Petr struggles to repair his damaged relationships while wrestling with his own internal flaws and inability to commit.
