Chiwetel Ejiofor

played DI Jonah Gabriel in The Shadow Line

Jonah seems to be an honest and good policeman. Returning to work after being shot during a botched operation. His memory of the incident is gone due to the bullet being lodged in his brain.
He is left doubtful of his own moral standing and his co-workers suspect he is
not above suspicion. While following a very complex investigation, Jonah is left wondering
at every turn, who he can trust, least of all, himself.
