Brielle Manders. She's just your average 22 year old girl with a small temper. She's also a gymnastics instructor who lives in a small apartment in Ninjago city with her roommate. Little did she know, on one lazy Saturday, that the arrival of four guys in ninja suits would change her life forever.

Jack Frost was sent to find some new guardians, when he found the perfect ones all together in a tower hidden inside the forest. He finds a red headed girl, a guy with shaggy brownish or blackish hair and a girl with long blonde hair, all he had to do was convince them, they're gonna have to train at North's place a lot if they have to defeat Pitch, who is by the way trying to crush children's spirits again. Can they do it?
