It was a reunion of seven friends. It was a joy ride on a luxury yacht through the middle of a beautiful ocean. It was time to remember the good old times. It was time to catch up on the lost five years. It was time to come face to face with unrequited love. It was Sara's first birthday. It was time for champagne. It was time for a swim. It was time for disaster to strike. Seven friends, neck deep in water, oblivious to the dangers that lie beneath, miles away from land with no way to get back on the yacht while Little Sarah cries incessantly aboard it. Old conflicts resound and new ones emerge while a predator comes to kill. This one eats flesh!!! 'Warning' is a underwater film about seven friends stuck in a life- threatening crisis. The lucky ones will die first and the rest will go through the worst nightmares of their lives.
