While the police meticulously follow up on every lead, a stranger with clearly a few screws loose, comes to tell Marie about a mysterious cave in the woods behind their property. He insists she can find her baby there. And he’s willing to give her a detailed map, on the sole condition that Marie describes in detail what she’ll see inside. Frightened, skeptical, but a mother above all else, Marie takes the bait and returns not only with her son safe and sound, but also with a massive memory lapse. But is it really their adorable little one? Fasten your seatbelts, because IMPOSTERS is going to rock your world!
