The Divide is a story about the drama of ordinary life, following Sam Kincaid, who is suffering from the onset of dementia in 1976, when Alzheimer’s did not yet have a formal name. Sam is supported by an unlikely ally in migrant ranch hand Luke, who summons Sam’s estranged daughter, Sarah, to help with Sam’s growing memory lapses. The film is set in one of the worst droughts in California history, a plight that mirrors the dry patches in the characters’ lives.
