Cléo is just six years old. She adores Gloria, her nanny who has been raising her since her birth. However, Gloria must urgently return to Cape Verde to be with her own children. Before her departure, Cléo asks her to make a promise: to see each other again as soon as possible. Gloria invites her to visit her family and her island, to spend one last summer together. Presented as the opening film of the Cannes Critics' Week, Marie Amachoukeli (Party Girl) draws inspiration from her childhood to create a second feature film that is both tender and deeply moving, punctuated by beautiful animated sequences.
