Dylan, David, Louise and Alicia set off to Calais to offer medical assistance at a refugee camp. There, Alicia takes a shine to British medic Cameron Hamilton, who has been on the scene for a while, helping the camp's women and children. Meanwhile, Dylan forms a bond with two children, Sanosi and Mariam, who have fallen prey to ruthless people-traffickers, and has to make a difficult decision about their future. Back at the hospital, Connie is shocked to learn Sam has resigned and seems to have disappeared - taking Grace with him.
