Leo doesn't steal priceless paintings or jeweled daggers. He steals moments. A forgotten harmonica from a nursing home, a specific brand of cherry lip balm from a pharmacy, a single, worn ticket stub from a 1980s cinema. His mysterious client, The Curator, then uses these objects to weave impossibly vivid, immersive memories for his wealthy clients, a chance to relive a first kiss, a last goodbye, a perfect summer day. For Leo, it's a way to use his peculiar talent for emotional resonance without getting hurt. But his latest assignment is different: steal the grief from a locket belonging to a woman named Clara, who is drowning in the loss of her husband. The job goes wrong, and Leo is left with a shard of her devastating sorrow lodged in his own soul. To free himself, he must unravel the real story behind the memory he was hired to steal, confronting his own past and The Curator's true, terrifying ambition.
