Toby (Craig Olejnik) and Oz (Ennis Esmer) are called to a crime scene to discover two victims lying in a pool of blood. Toby senses someone else is present, and the victim's teenage son, Andy (Mark Rendall), is discovered hiding and barely alive. Toby is overwhelmed with thoughts and voices. With two dead parents and the only witness unable to speak, Charlie asks Toby to use his telepathic ability to explore Andy's mind. Their investigation reveals Andy may suffer from a rare and puzzling condition. When Olivia's annoying sister Jennifer (Mayko Nguyen) arrives in town, she asks Toby and Oz to help provide a distancing barrier between the rival siblings.
