Masterpiece! One of my favourite films ever!

The film is packed with omnious, horrifying scenes and it is based on true events at the same time. It has many merciless scenes but they are realistic. Furthermore, the cast is great as well and they authentically represent different states of human psyche and patterns of behaviour during hard times while being locked in hospital. Some of them behave like cowards and some fight bravely with disease and help everyone in need even though it can cost them their own life. In my opinion this film isn't nearly as popular as it should be, especially that we all faced global pandemic not a long time ago.
