Shell suits, colourful jackets, big tape recorders, video players, video rental shops at every corner, new social conditions, a flood of various crooks, incipient organised crime and the violence and corruption that goes with it. Director Jonáš Karásek and screenwriter Tomáš Dušička portray the environment of the turbulent 1990s through an action-packed dark comedy. The story of Laco, a museum janitor prone to choleric attacks, is set in an anonymous Slovak small town. Due to his nature, he finds himself in the wrong place at the wrong time, resulting in an injury that will scar him for life. Seeking revenge, he embarks on a dangerous mission against the local mafia with his new friend Gabo. Thanks to its audience appeal, Invalid has become one of the most-popular films of the year.
