Spark may be a cute and cuddly teddy bear, but she's also a fierce protector. Weeks after rescuing her human owner--a budding young filmmaker named Loretta--from a hideous monster, everything seems to be returning to normal. But then Spark is summoned before the mysterious Grand Sleuth, the high council of teddy bears, who task her with a dangerous mission: locating the portal to the monster's world.

During her daring quest, Spark discovers a terrible secret that changes everything. In order to keep Loretta and their whole town safe, she must enlist the help of her loyal toy friends and team up with an unexpected ally. As the menace grows, Spark realizes that Loretta has a hidden power that may be the key to saving them all . . .
