Much to Dylan's disappointment, his best friend, Mindi, takes pity and invites her into their inner circle. As Mindi and Belinda grow closer, Belinda lights up with new-found confidence while Mindi becomes cold and reclusive, distancing herself from Dylan and his friends. As this increasingly abnormal behaviour becomes intertwined with eerie supernatural forces, Dylan is compelled to dig deeper into Belinda's true character, but what he discovers next is something more sinister than he ever expected.
