<P> In 2020, the Becket brothers, Raleigh and Yancy, pilots of Gipsy Danger, are launched to defend Anchorage from Knifehead, a Category III Kaiju . Knifehead kills Yancy, and Raleigh barely manages to pilot the Jaeger on his own and kill the Kaiju before crashing it at a shoreline . Traumatized by Yancy's death, Raleigh quits the Jaeger program . Five years later, the increasing power and numbers of the Kaiju cause the world governments to end funding for the continuous construction of Jaegers in favor of building coastal walls, and Marshal Stacker Pentecost moves all four remaining Jaegers to the last Jaeger Shatterdome in Hong Kong and plans to end the Kaiju War by destroying the Breach with a nuclear weapon . As Striker Eureka, piloted by Herc Hansen and his son Chuck, kills Mutavore, a Category IV Kaiju, in Sydney, demonstrating the ineffectiveness of the walls, Pentecost persuades Raleigh to rejoin the program and they arrive at Hong Kong and meet Mako Mori, director of the Jaeger restoration program . After finding her compatible, Raleigh and Mako try their first drift, but Mako ends up nearly destroying the Shatterdome while lost in the memory of a Category II Kaiju attacking Tokyo and killing her family, and is relieved of piloting duty . It is revealed that after this incident, Mako was saved and raised by Pentecost . </P> <P> Pentecost consults Kaiju experts Newton Geiszler and Hermann Gottlieb to plan the assault on the Breach . Newton is able to drift with a piece of a Kaiju brain, discovering the Kaiju are scouts sent by invading beings from another dimension, and establishing a two - way mental link that enables the Kaiju hive mind to gain access to his knowledge just as he did theirs . Pentecost tasks Newton with finding a black market dealer and seller of body parts of dead Kaiju, Hannibal Chau, to find a fresh Kaiju brain . Later, two Category IV Kaijus, Leatherback and Otachi, emerge and rampage through Hong Kong to find Newton . After Otachi destroys Crimson Typhoon and Leatherback destroys Cherno Alpha, Striker Eureka loses all power by Leatherback's EMP blast . Gipsy Danger is finally sent and kills both Kaijus . Newton and Chau find out that Otachi is pregnant, and the infant Kaiju dies shortly after swallowing Chau whole . Newton and Hermann drift with the infant's brain, discovering the Breach will only open in the presence of a Kaiju's DNA . </P> <P> As Herc was injured during the previous fight, Pentecost, who is dying from radiation sickness from piloting a Jaeger with a nuclear core before the implementation of radiation shielding, gives a rallying speech and pilots Striker Eureka with Chuck . Along with Gipsy Danger, they approach the Breach and are warned by Newton and Hermann of what they discovered from drifting with the infant's brain . Three Kaijus, two Category IV called Scunner and Raiju and a first Category V named Slattern, emerge from the Breach to defend it . After Raiju is killed, Pentecost and Chuck sacrifice themselves by detonating the bomb, which kills Scunner and wounds Slattern . Raleigh and Mako kill Slattern and drag it to the Breach, where Mako is ejected and Raleigh successfully overloads the Jaeger's reactor, destroying and closing the Breach . As Raleigh and Mako's escape pods surface in the Pacific Ocean, Herc orders the war clock to be stopped, indicating mankind's victory and Raleigh and Mako embrace . </P> <P> In a mid-credits scene, Chau is shown cutting his way out of the Kaiju infant, looking for his lost shoe . </P>
