Alex was rescued by aliens when he was a baby. Now, he is 12 years old and works with them to capture cryptid creatures (like Bigfoot and the Loch Ness Monster) placed on Earth after the aliens’ spacecraft engine malfunctioned. When a cryptid vanishes from the aliens’ monitors, they send Alex on an emergency mission to uncover what happened. There, Alex encounters something more dangerous than the creature he was sent to recover.
