Lorelle gets the chance to travel back in time to stop her father from ruining her life.
Growing up she had always believed that her father had blown up a school. She travels back in time and gets to know her younger self, and her parents, discovering that there may be more to what happened.
She sees her father in a light she had forgotten, a gentle and kind man. Questioning what really happened she tries to prevent him being at the school.
In the end she follows him there, only to discover that her father didn't set the bomb, but was trying to discharge it. His selfless act meaning that he saved countless lives.
This episode really did have great acting, I especially liked Paul Popowich in the role of Thomas, which after only having seen him play Mr Smith, was really great.
