Setting: Hawaiian underwater mountains
Blue Team is a group of undersea explorers previously led by the adventurous Paul. However, when they are sent on a dangerous mission to take close up photography and video of the famous Krakachoa and try to discover its mythical cave, a marine biologist is put in charge: Paul’s girlfriend Tina.
As Paul struggles to cope with working under Tina’s authority, engineers Bradley and Marco find themselves falling in love with, respectively, ship’s medic Claire and Heather, Paul’s sister. But as they have been warned, science has shown that canoodling is poisonous in deep water.
As all relationships are tested in various ways, will Blue Team survive?
