Battleship (2012) - Movie

In 2005, NASA discovers an extrasolar planet with conditions similar to Earth. On the chance that it contains intelligent life, NASA transmits a powerful signal from a communications array in Hawaii, which will be boosted by a satellite in orbit. Around the same time, the talented but undisciplined slacker Alex Hopper (Taylor Kitsch) attempts to impress a woman by getting her a chicken burrito; the result of which sees Alex break into a convenience store and be tasered by the police later. The woman is later revealed to be Samantha Shane (Brooklyn Decker), daughter of United States Pacific Fleet commanding officer Admiral Shane (Liam Neeson), who in turn is the superior of Commander Stone Hopper(Alexander Skarsgard), Alex's elder brother. Fed up and infuriated at Alex for lack of motivation and possibly ruining his own career, Stone forces him to join the United States Navy.
By 2012, Alex is a lieutenant and the Tactical Action Officer aboard the destroyer USS John Paul Jones, while Stone is the commanding officer of USS Sampson. Alex is also now in a committed relationship with Samantha, and wants to marry her, but is afraid of asking her father for permission. During the opening ceremony for the RIMPAC multinational naval exercise, Alex gets into a brawl with Captain Nagata (Tadanobu Asano), commanding officer of the Japanese Maritime Self Defense Force destroyer JDS Myōkō; the latest in a string of incidents marring the young officer's career. Alex is given a dressing-down by Admiral Shane, and later learns from his brother that there is a good chance he will be discharged at the end of RIMPAC. Meanwhile, Samantha, a physical therapist, accompanies retired Army veteran and amputee Mick Canales (Gregory D. Gadson) on a hike on Oahu in order to help him adapt to his prosthetic legs.
A small fleet of five alien ships arrives in response to the NASA signal. One ship collides with an orbital satellite and crashes in Hong Kong, while four others land in the waters near Hawaii. Sampson, John Paul Jones, and Myōkō are sent to investigate, but are trapped when one of the ships erects an impenetrable force field around the Hawaiian islands.
The three destroyers attempt to establish contact, but the aliens open fire: Sampson and Myōkō are destroyed, with the entire crew of Sampson annihilated, including Stone, and John Paul Jones is damaged with the commanding and executive officers killed. Initially attached to Sampson, Alex, who was one of the few out to take a closer look at the alien vessels, now boards John Paul Jones. Being the most senior officer left on the ship, he is forced to take command. Although initially wanting to attack the alien ships in retaliation for his brother's and his crew's death, Alex is convinced to break off and recover survivors from Myōkō, with Captain Nagata among them; this act prompts the aliens to call off another attack. Although the barrier is preventing the use of radar and sonar, Nagata reveals that they could use the tsunami warning buoys around Hawaii to track the alien vessels' movements by their displacement.
During a night-time battle, the aliens and the humans exchange pot shots, with John Paul Jones sinking two, but unable to lock onto the third. An alien soldier is recovered from the water; from the brief contact with the alien, the humans determine that the aliens are very sensitive to sunlight. Alex uses his ship to lure the alien vessel close to shore, where he and Nagata shoot out its bridge windows at sunrise, then proceed to fire at the alien vessel full force. Both ships are destroyed in the ensuing battle.
Because the ship that crashed in Hong Kong was their communications ship, the aliens land soldiers on Oahu and take over the area around the array while using it to signal their home planet. Samantha and Mick narrowly avoid detection and run into a fleeing NASA scientist. Believing that a much larger invasion might be imminent, the scientist goes back to the array and gets a radio, which Samantha uses to warn Alex. He had planned to destroy the array with his ship, but since John Paul Jones has been destroyed, the survivors are forced to return to base and acquire the only available naval vessel, the battleship USS Missouri. Although a museum ship, Alex and his crew are able to reactivate Missouri with the aid of the retired old veterans preserving her. The battleship engages the alien ship and destroys its barrier but ends up with only one high-explosive shell left. Alex uses it to fire on the array, but before the defenseless Missouri can be attacked one more time by the now-decimated alien ship, fighters from the RIMPAC fleet (which scrambled to attack as soon as the barrier was gone) arrive and eliminate the alien ship, while the NASA array explodes, destroying all the aliens and their equipment.
Back on shore, the naval personnel, along with Mick, are honored for their actions.
