Season One (2009)
Toby is a 28-year-old first year paramedic who never knew his father and grew up in foster homes. Until now, Toby has kept his ability to listen to people's surface thoughts a secret and the only one he has shared it with is his old counsellor and confidant, Dr. Ray Mercer (Colm Feore), prior to the series' first episode. While he crosses the city of Toronto in his ambulance with his partner Osman "Oz" Bey (Ennis Esmer), Toby helps people in crisis and on the way come to terms with his own past. With the help of Detective Charlie Marks (Lisa Marcos) and his on-and-off girlfriend Olivia Fawcett (Mylène Dinh-Robic), an E.R doctor, Toby realizes that his gift can serve to help other people.
Season Two (2011)
It's a year and a half later and Toby has finally come to terms with his telepathic powers and is still working with his paramedic partner Osman Bey. After assisting with an undercover case investigated by the Integrated Investigative Bureau (a special unit of the Royal Canadian Mounted Police) Toby reveals his gift to Sgt. Michelle McCluskey (Lauren Lee Smith). Despite her initial scepticism, she realises that Toby's special abilities could be her team's secret weapon. So alongside his paramedic work Toby joins Michelle and other members of the IIB to help solve some of their most difficult and high-profile cases ranging from suspicious homicides to cases of arms dealing. But the price to pay for having such a gift is the emotional and physical effects of delving into some of the most deranged criminal minds out there and it is his old flame Dr Olivia Fawcett who helps him deal with his problems.
