In 2005, NASA discovered an Earth-like planet outside the solar system and determined that there might be intelligent life on it. In order to contact extraterrestrial intelligent life, NASA launched the "Lighthouse Project" and activated the deep space communication array base in Hawaii to send high-power signals to it for exploration. A few years later, alien spacecraft arrived unexpectedly. The Pacific Joint Navy Exercise Fleet in Hawaii was ordered to make contact. The missile destroyer where the protagonist, Navy Lieutenant Alex (Taylor Kitsch), and two other warships were used as a reconnaissance team and were ordered to contact alien ships. However, they were attacked and suffered heavy losses. Due to the shields deployed by the alien ships, other ships of the joint fleet could not provide support and could only rely on themselves to support. In the end, all three modern ships were destroyed. Since there were no ships available, but the communication station occupied by aliens had to be destroyed, the battleship Missouri, which had been converted into a maritime museum, could only be used for the final attack. The ace battleships of World War II faced alien high-tech ships. Who will win? What is the fate of the earth?
