Return from the Deep

Eight months pregnant, Emma is murdered by her husband Daniel and best friend Chloe. Drugged and locked in an abandoned seaside observatory, they wait for the tide to wash her away, plotting to stage an accident and seize her family's beer empire. In desperation, Emma goes into premature labor and desperately tries to survive by throwing bottles into a bottle for help. Her amnesiac, faked-death brother secretly investigates the case, while her mother discovers the conspiracy and freezes the assets. Ultimately, Emma is rescued and appears at the villains' party with her newborn daughter, publicly exposing their crimes and bringing the two to justice.
