De jonge spierbonk Tadeás Falk, bijgenaamd Táda, bezorgt vlees vanaf het slachthuis naar Liberec en omstreken. Hij en de gescheiden Bára Saklová moeten zo snel mogelijk trouwen, zodat Bára een bedrijfsflatje kan krijgen waar ze dan kunnen wonen samen met haar vijfjarige dochtertje Beruska, die nu nog bij Bára's moeder woont. Haar ex, hotelmanager Sakl, zit haar telkens dwars. Hij kan het niet uitstaan dat Táda straks de stiefvader van Beruska gaat worden.
Nee, helaas is Křehké vztahy nog niet beschikbaar op Netflix in Nederland.
