While vacationing by the Baltic Sea, writer Leon and photographer Felix are surprised to encounter Nadja, a mysterious young woman staying as a guest at the holiday home of Felix's family. Nadja soon distracts Leon from finishing his latest novel, not only because of her passionate liaison with lifeguard Devid but also because her brutal honesty forces Leon to confront his artistic inadequacies. As Nadja and Leon grow closer, an encroaching forest fire threatens the group and pushes the writer to discover whether he can truly care for anything beyond himself.
