Berlin - a large market of singles of all ages. While account-manager LINA (28) scrolls through blurred pictures and academic CV's to find a father for her future children, pensioner PETER (72) sits in his bower and chats with Elena from Siberia. LUCAS (23), too shy to flirt openly, uses an app with radar function to find the man of his dreams. BARBARA (47) has lost her belief in 'the one and only'. Living an open relationship, she looks for dates on erotic websites. The documentary BIETE.SUCHE follows their digital search for a new partner.
