Seven-year-old Chula and her older sister Cassandra enjoy carefree lives thanks to their gated community in Bogotá, but the threat of kidnappings, car bombs, and assassinations hover just outside the neighborhood walls, where the godlike drug lord Pablo Escobar continues to elude authorities and capture the attention of the nation. When their mother hires Petrona, a live-in-maid from the city's guerrilla-occupied slum, Chula makes it her mission to understand Petrona's mysterious ways. But Petrona's unusual behavior belies more than shyness. She is a young woman crumbling under the burden of providing for her family as the rip tide of first love pulls her in the opposite direction. As both girls' families scramble to maintain stability amidst the rapidly escalating conflict, Petrona and Chula find themselves entangled in a web of secrecy that will force them both to choose between sacrifice and betrayal.
