Lamar Johnson (The Hate U Give, 2018) and Aaron Pierre (The Underground Railroad) play the inseparable Jamaican-Canadian brothers Michael and Francis. Every night, before leaving for work, their mother (Marsha Stephanie Blake) gives them strict instructions to stay indoors and keep the TV off, but the two inevitably become entangled in what’s going on outside, both in person and through nightly news reports. Michael, a timid teenager, is always protected by the slightly older Francis, who, in their father’s absence, steps up to be his mentor.

Ten years later, Francis is gone and Michael, unmoored, struggles to take care of his mother, who is now incapacitated by grief. The film slowly pieces together their tragedy, jumping back and forth through time to capture its weight, and to track how a mother’s painstaking efforts to protect her children can only extend so far.
