Low Tide tells the story of the last three days of a woman's life. Kathy is dying of cancer and is being nursed at home. Her husband Tom cooks and cares for her but is unable to offer her emotional support and keeps himself apart, playing his music or drinking with a recently widowed friend. Kathy forms a strong attachment to her visiting nurse, confiding in her about her past affairs, her ambiguous feelings towards Tom and her fear of death. Her closest friend comes to visit and a rift is healed. Memories haunt her and eventually, after a painful confrontation, she and Tom attempt to come to terms with her infidelities, their unhappy marriage and the loss of their only child.
