Unable to return to work due to the psychological trauma sustained during a failed rescue mission, an increasingly frustrated and volatile Theo's world is rocked when one morning, he wakes up next to his wife's murdered corpse with no recollection of what transpired and all evidence suggesting that he's killed her.

When connecting the dots becomes a matter of life and death, Theo becomes embroiled in a desperate fight for survival and must figure out who really murdered his wife before a terrifying conspiracy changes the course of a nation forever.
