Nachbarinnen (2005)

aka Nuits Blanches

The single package-delivery woman Dora lives a somewhat reclusive life in a high-rise in Leipzig and gets through everyday life with her dry sense of humor. But her quiet, well-ordered life spins out of control when she has to hide her mysteriously fascinating Polish neighbor Jola – who believes to have accidentally killed someone. Dora is hesitant at first to take her in, but she cannot seem to shake her fascination with Jola. Dora's trust in the direct, impulsive woman grows – Jola seems to ask exactly those questions no one else dares to ask. When Dora finds out that the accusations against Jola have been lifted, she lies about the status of the police investigation in order to keep her Polish neighbor for herself.
