Jacob Kanon, a New York detective, investigates the death of his daughter who was murdered while on her honeymoon; he recruits the help of an American journalist working in Sweden, Dessie Lombard, when other couples throughout Europe suffer a similar fate.

In June 2012, it was reported James Patterson was working with European producers to adapt his novel The Postcard Killers that he had co-authored with Liza Marklund to film.

[7] In May 2019, it was reported Famke Janssen would be replacing Nielsen as Valerie and that Kamiński had left the film which would be now directed by Danis Tanović.
