Undercover detective Luca is tasked with assassinating crime boss Dante, but after the mission goes awry, he is marked for death by his own side—only to be saved by Dante himself. From bitter enemies, the two become secret allies, and as they investigate a conspiracy involving both the police and the underworld, they gradually fall in love. Their bond shatters when Dante discovers that Luca is not only a cop, but the very assassin sent to kill him. Though lies drive them apart, they cannot escape the choices that follow. Ultimately, they join forces to uncover the truth behind a cold case from fifteen years prior, and in the same church where they first met, they choose each other once again.
