The weather takes a turn for the worse, causing an emergency at sea and threatening to make one young British couple's wedding a washout. It is the first time new officer Lauren has to deal with an emergency on board and she must keep constant watch on a semi-submerged boat close to the liner. Concerned there may be lives at stake, the rescue team are poised for action. Despite choppy seas, the show must go on in the ship's theatre, where the magicians are attempting to pull off a gravity-defying illusion that sees ex-dancer Trish balance on the tip of a metal sword. It is a heartstopping performance for passengers as the unpredictable weather ramps up the danger of their daring headline act.
