Zac arrives for his first day at Heartlake International High School, and Aliya is so excited to introduce her cousin to all her friends. But will the pressure of making a good impression be too much for Zac?

After making a disaster at a science experiment in school, the friendship between Aliya, Autumn, Liann and Nova is a bit strained. Therefore, Autumn hosts a sleepover at her barn to lighten the mood and for them to work on their friendship. But everything is not as comfy as it seems to be. What was that sound? Did we see a shadow? Could it be that the barn is haunted? The girls will have to work together to figure out the mystery.

Expressing her anger through art, Liann draws a rude picture of Nova. But when the picture gets out, Liann must track it down before Nova sees it. Meanwhile, Zac and Aliya clash as roommates, because Zac is not as good at keeping their shared space tidy. Will the friends be able to work out their differences and see eye to eye?

Unaware that they have the answers to each other's problems, Nova fails to make a popular video game, while Autumn struggles to help a puppy in need.

When all of the dogs escape from the Adoption Center, Nova recruits her friends to track them down before Autumn realizes they're missing.

The friends come together and do what each of them does best to come up with the best idea for this year’s big initiative! Their idea is to turn the annex into a big community center full of creative opportunities for the whole city. Aliya is the idea maker along with Leo and Zac, Olly is the filmmaker, Liann the creative and Paisley becomes the entertainer after the friends discover the perfect song for her to play. Can the friends save the annex?

The friends decide to run a street fair to raise money for the new community center. Since it was his idea, Leo wants to lend a helping hand wherever he can, but can he be in three places at once?

When Aliya finds herself struggling to choose only one of her friends' many ideas for what should go inside the new community centre, she must find a different solution.

After hurting her ankle, Aliya tries to escape the nurse's office. Paisley and Olly must find a new performer for the community center opening ceremony.

Christmas arrives at Heartlake. Zac needs volunteers for a snowboarding competition, while Leo and Paisley hang decorations and cook at the restaurant.
