Watch Godzilla vs. the Sea Monster

Ryota's brother is lost at sea and he is desperate to find him. So desperate that he and his friends steal a yacht. What they don't know is that the yacht belongs to a bank robber. Their troubles only get worse when they encounter a giant lobster named Ebirah. The monster attacks their boat. Luckily, the four men wash up on the shores of a nearby island. As they set out to explore their new surroundings, they discover the island is under the control of the terrorist organization known as Red Bamboo. The group has been capturing natives to use as their slaves, and has developed a chemical to control Ebirah.

Caught between the terrorists and a giant lobster, Ryota, his friends and an escaped island girl named Dayo come up with a desperate plan. They have discovered Godzilla sleeping under a mountain. Erecting a make-shift lightning rod, they intend to wake the King of Monsters and have him fight Red Bamboo and Ebirah.

But Red Bamboo is hiding a secret, one that could prove deadly to Ryota, his friends and Godzilla.
