Jack Spinosa (Ciaran Bird) and his wife Katrina (Hollyoaks star Beth Kingston) were attacked and found shot in an alley on June 5th 2009. Jack miraculously survives the attack but wakes up with complete amnesia, with no memory of the event at all or anything that has happened before it. In an effort to determine what happened and who murdered Katrina Detective Charles Kolbur (Shezai Fejzo) and the police department invite Jack to join the investigation team in the hope that exposure to clues, suspects and the scene will bring back Jacks memory and hopefully put the culprit behind bars. However as Jack begins his investigation he soon learns more about Katrina's life than he originally knew and that nothing is what it seems.
