The Case of Unfaithful Klara

Luca, a talented young Italian musician, lives in Prague with his girlfriend Klára, a very pretty university student of whom he is insanely possessive of. Obsession and suspicion induce Luca to hire private detective Denis to keep tabs on Klára to find proof of adultery. Denis is attractive, slightly ironic and cynical, clearly the opposite of Luca. He and his wife Ruth have a very open relationship, in which Ruth makes no secret of her adventures with other men. Denis, on the other hand, is having a love affair with a colleague from the detective agency, Nina, a divorced mother of two. Although the disconsolate Luca gradually gains Denis’ sympathy, the detective starts to yield to Klára’s charms and to abandon his own principles, which can have tragic consequences. The sleuthing will take the main protagonists to the magical city of Venice, culminating in an unexpected finale that confirming that not everything or everyone is what or who they seem to be.
