Rebellious teenager Kim Temple (Louisa Connally-Burnham) has a troublesome affliction: in stressful situations she loses consciousness and during these so-called sleeping fits she can travel through her own past. During one of these episodes, she witnesses a disturbing moment in the past involving the man she fears so deeply, namely her father. Kim realises that if she can uncover the truth about the unsettling event, she might be able to keep her father locked up in prison. But in order to achieve this, Kim must force herself into increasingly dangerous situations, as this is the only way to enter a sleeping fit. On top of this, each journey to Kims past has a negative impact on her health. Can she reveal the truth before her quest kills her?
