Spencer Mendes, Shawn's sister, plans to leave her family for her dreams of singing. Before she ever starts the global craze called Vine, she decides to leave, forgetting that she ever had a family. She moved to California, starting her new life in Chino Hills, starting school as a senior. She then meets a guy named Cameron, who introduces her to the app, Vine. She starts doing covers, and she becomes famous, and she is offered a spot on the Magcon tour. She leaves with Bart, going off to North Carolina to meet up with the rest, only to find out that her brother was on the tour too...

Cameron Dallas -- Vine-famous sensation, with girls of all ages obsessing over him. Any girl would be lucky to meet him, let alone go to school with him. Allison Lawrence -- The only girl who doesn't care who Cameron is. The only girl who wants Cam, not "Cameron Dallas". The only girl on his mind.
