Orca

In the cold waters of the Atlantic, a vengeful orca, driven by a desire for justice and fueled by the memory of its slaughtered mate and unborn calf, sets out to confront the humans responsible for its grief. As the body count rises, a marine biologist and a seasoned fisherman join forces to stop the whale's reign of terror, but their efforts may be too little, too late. Will the orca's thirst for revenge be quenched, or will it continue to wreak havoc on the fishing village and its inhabitants?
