In a world where time flows in reverse, Elias Vayne, a disillusioned private investigator, stumbles upon a murder that has yet to be committed. A man lies dead—until he rises, blood retreating into his veins, as an ambulance returns him to the scene of his own undoing. The murderer, a shadowy figure in black, appears holding a smoking gun—just before a bullet miraculously ejects from the victim's body and shatters the firearm in his hand.

Elias should walk away. He should let time consume the past and erase the crime before it ever happens. But something about this case won't let go. The victim is the husband of Elias's lover, and the woman's grief—playing in reverse as she is "consoled" into fresh heartbreak—gnaws at him. As he traces the crime backwards, every clue that appears was already hidden, every answer is a question waiting to be asked. The murderer moves away from the scene, each step erasing his presence, yet Elias knows he is hunting a man destined to pull the trigger.

With time itself conspiring against him, Elias follows a trail of evidence that assembles itself from destruction—burned papers reform, shattered glass reassembles, and a locked safe slowly unseals to reveal a secret that should never have been buried. As the case unspools, Elias discovers that the murder is not just a crime of passion but the key to a larger conspiracy—one that stretches into a future that no one remembers.

The closer Elias gets to the truth, the further it slips from reach. Justice, in this world, is not about punishment—it's about prevention. And when the final moment arrives, Elias faces a choice: let the murder remain undone or become the one to ensure it happens.

Murder Undone is a razor-sharp noir thriller, blending existential mystery with a mind-bending inversion of causality. Can a crime be solved before it is committed? And if time moves backward, is guilt predetermined—or is fate just another illusion?
