A Black British woman adopted at birth (Marianne Jean-Baptiste) tracks down her biological mother, who turns out to be a working-class white woman (Brenda Blethyn, in a Palme d'Or–winning performance) with secrets of her own. Mike Leigh's Secrets & Lies—winner of the Palme d'Or at Cannes—is a deeply compassionate drama about family, identity, and the cathartic power of truth, built from Leigh's signature process of collaborative improvisation and anchored by two unforgettable lead performances.
