Thriller in which a group of friends go on a sailing trip to celebrate the 30th birthday of one of their group. But the party atmosphere quickly dissolves when, having left the boat to swim in the ocean, they realise they have forgotten to put a ladder down. They're miles out to sea and have no way of getting back on board. No one can hear them and all they can hear is the lonely cries of the unattended baby on deck. Eric Dane, Susan May Pratt and Richard Speight Jnr star in a film which was pitched to American audiences as the sequel to the equally haunting Open Water.
