Two old friends of Sam and Jack have come to Hope Island. They are a husband and wife team of wildlife documentary makers. During some filming on the reef, the anchor of their boat comes lose and the tide takes it away from them. When the boat is found empty and adrift, a search and rescue mission is mounted. Not knowing where they had dived meant that it was going to be a very long search. Meanwhile, one of the local police officers has come down seriously ill with an abnormally fast heart rate. The exact remedy causes Rick some anxious moments. Written by
