Bloodlands - what's it all about?
A synopsis of the opening episode from the BBC shares: "A car is pulled from Strangford Lough, the owner kidnapped. DCI Tom Brannick (James Nesbitt) recognises the calling card of a legendary assassin known as Goliath.
"The legend goes that he was a serving police officer who vanished without trace 20 years ago - and among his original victims was Tom’s wife.
"Against opposition from old friend DCS Jackie Twomey (Lorcan Cranitch), Brannick and his partner, DS Niamh McGovern (Charlene McKenna), break open the Goliath case in the hope that it will help them solve the kidnapping. As they dig deeper, they find gaps in the original Goliath investigation. Someone tried to suppress the truth.
"When a vital clue leads them out to an island on Strangford Lough, a discovery is made that changes everything."
Bloodlands begins Sunday, 21 February at 9PM on BBC One.
