Waves (Czech: Vlny) is a 2024 Czech-Slovak historical thriller drama film written and directed by Jiří Mádl and set during the Prague Spring and subsequent Warsaw Pact invasion of Czechoslovakia.

Other journalists include Věra Šťovíčková, Jiří Dienstbier, Luboš Dobrovský or Jan Petránek.

Tomáš is forced to sign cooperation with StB if he wants to protect his brother who along with his classmates participates in illegal activity.

Tomáš gets closer to journalists in the office especially with Věra which leaves him conflicted between concern for his brother's safety and his own conscience.

When Warsaw Pact invades Czechoslovakia, he refuses to collaborate with occupants and helps journalists to broadcast uncensored information about the invasion of Warsaw Pact troops and call for passive resistance to the occupiers.

Mádl based the film on the memories of contemporary witnesses, including the journalist Jan Petránek and especially Věra Štovíčková, from whom he learned things that cannot be found in textbooks.
