Seamlessly blending humour with grounded body horror, DON'T LEAVE HER ALONE , tells the story of a mother and two sisters - each also a mother to young children - linked by the tentacles that live inside them. Alba has spent her life unable to be alone, clinging to the presence of others to silence the anxieties she refuses to face. But when she wakes up on the floor of a shopping mall, covered in blood and with only fragmented memories of how she got there, she is forced to confront the truth she has long avoided. Meanwhile, her sister Diana struggles to balance the pressures of motherhood and work, drowning in guilt and anxiety, while their mother, Carmen, remains trapped in an endless cycle of sacrifice and duty, caring for her daughters and grandchildren. As Christmas Eve approaches, the tension between them becomes unbearable and what once seemed like ordinary family struggles transforms into a surreal nightmare. Rooted in the unsettling familiarity of a suburban shopping mall and the halo of childhood nostalgia, DON'T LEAVE HER ALONE is both an eerie and witty portrait of what happens when fear is left unchecked - festering within us until it consumes us from the inside out.
