Toby is a 28-year-old first year paramedic who's never known his father and grew up in foster homes.Until now, Toby has kept his ability to listen to people's mind a secret and the only one he has shared it with is his old counselor and confidant, Dr. Ray Mercer, prior to the series' first episode. While he crosses the city of Toronto in his ambulance with his partner Osman "Oz" Bey , Toby helps people in crisis and on the way come to terms with his own past. With the help of Detective Charlie Marks and his on-and-off girlfriend Olivia Fawcett, an E.R doctor, Toby realizes that his gift can serve to help other people.
Toby is called as a witness in the murder trial of a young singer allegedly shot by her overbearing producer. Having broken EMS protocol by bashing down the door before the police have arrived, the defense is trying to destroy Toby's credibility.
