The North Water

BBC2, 9.30pm

Rations are running low and Sumner offers his ring in exchange for seal meat from two Inuit men. As hunger and exhaustion take hold, Drax sees a daring opportunity for freedom, but needs help from Cavendish. Meanwhile, Sumner shoots at a bear and tracks it through the snow past the point of no return. Close to death and with one shot left, can he find a way to survive? ★★★★★
