The Silence (1963)

Adult sisters Ester and Anna and Anna's ten year old son Johan are traveling across Europe by train trying to make their way home. Despite the country being on the brink of war, they make an unscheduled stop in Timoka in Central Europe as Ester is too unwell to travel, they ending up staying in a small suite in an otherwise virtually empty hotel. At this stage, Anna is tasked with taking care of Ester despite the two sisters having more than just a strained relationship. The sisters are also different in temperament, Ester, a translator of books, who is more focused on her brain, while Anna, largely uses her physicality (i.e. sex) to satisfy her needs. At the hotel, Anna ditches both Ester and Johan at whatever opportunity she can to satisfy her needs. Meanwhile, Ester continues to work whenever she feels well enough, while relying largely on the hotel steward working on that floor whenever she needs that assistance that Anna would have provided, and when she isn't self-medicating herself with alcohol. This situation between the sisters leaves Johan largely to his own devices, he who isn't told about how sick Ester really is, but who may be able to see the situation from his observer perspective.
