A company claims that a DNA test can identify the person each customer is destined to love. The promise turns romantic uncertainty into a lucrative business, while the people involved struggle with the consequences of treating a match as an answer to every question. Detective Kate Saunders encounters her own complications when her connection with Sophia draws her into a relationship with a life and history beyond the test result. Attraction, existing commitments and Sophia's connection with Valeria make their story more difficult than a technological guarantee suggests. The thriller links private desires to corporate power, asking whether knowing who might suit someone makes love any less dependent on choice and trust.
