'Kate, her brother Matt and his girlfriend Suzie arrive at the Great Barrier Reef in Australia to meet up with Kate's ex-lover Luke. Luke and his friend Warren deliver boats round the world for a living. Luke's offered to take his three friends sailing for a week on a boat he has to deliver to Indonesia. On the water Kate and Luke's relationship starts to reignite but it's fraught with old conflicts. Dawn, the next day. Suddenly the boat flips. There is a frantic struggle to save themselves and get on to the overturned hull. On top of the hull they see that the keel has been ripped away.
'Assessing the situation Luke decides their best chance for survival is to swim for a nearby island. Should they swim or should they stay? One of them refuses to go whilst the other four decide to try and make the island. As they swim they become aware that they are being stalked by a huge shark. Based on true events, The Reef is a tense survival thriller that begs the question, what would I do in this situation?'
