The people behind The Dark Knight trilogy and The Motorbike Girls unite for this dark psychological thriller. Mary Jago (Millie Bobby Brown, Stranger Things, The Bionic Woman), volunteers to donate some bone marrow against the wishes of her boyfriend, Alistair (Amir Wilson, His Dark Materials). When he finds out, she beats her so brutally, she breaks up with him and goes house-sitting for a rich couple in London. She then meets the leukaemia patient whose life she saved and becomes involved in a dangerous relationship with him and his mysterious brother.
