Six Four - The Complete Mini Series

All four episodes of the crime drama starring Kevin McKidd and Vinette Robinson. DC Chris O'Neill (McKidd) and his wife Michelle (Robinson), a former undercover officer, are desperate to find their missing daughter. When Chris digs into the old unsolved case of another teenager who has been missing for over a decade, he finds evidence of a cover-up and is concerned that his brother, Assistant Chief Constable Philip O'Neill (Andrew Whipp) might be involved.

Are the two cases connected?
