Loving Vincent (in german language)

One year after Vincent van Gogh's suicide, Postman Joseph Roulin asks his son Armand to deliver Van Gogh's last letter to his brother, Theo. Roulin finds the death suspicious, as merely weeks earlier Van Gogh claimed through letters that his mood was calm and normal. Armand reluctantly agrees and heads for Paris.

Père Tanguy, a Montmartre art supplier, tells Armand that Theo has actually died six months after Vincent. He suggests Armand to travel to Auvers-sur-Oise and look for Dr. Gachet, who housed Van Gogh after his release from an asylum, shared his love for art, and attended the funeral. Once there, Armand learns that the doctor is out on business, so he stays at the same inn that Van Gogh did during his time in the area. There he meets temporary proprietress Adeline Ravoux, who was fond of Van Gogh, and was also surprised by his death. Upon her suggestion, Armand visits the local boatman, who informs him that Van Gogh kept close company with Dr. Gachet's sheltered daughter, Marguerite. She denies and gets angry when suggested that Van Gogh's suicidal mood could have resulted from his argument with her father.

Throughout the investigation, Armand begins to suspect a local boy named René Secretan, who reportedly liked to torment Van Gogh, was in possession of a gun and had often drunkenly waved it around town. Doctor Mazery, who examined Van Gogh, also claims that the shot must have come from a few feet away, ruling out suicide. Marguerite confesses to being in close, but not romantic, relations with Van Gogh.

Dr. Gachet finally returns and promises to deliver Armand's letter to Theo's widow. He admits there was an argument between them – Van Gogh accused Gachet of being a coward for not pursuing his dreams, to which he angrily accused Van Gogh of being overly dependent on his brother, thus deteriorating his health. Gachet posits that the accusation drove Van Gogh to suicide in order to release Theo from the burden. Armand returns home, and Postman Roulin later receives word from Theo's widow, Johanna, thanking Armand for returning the letter – signed, "Your loving Vincent."
