A few weeks after a gigantic earthquake strikes Tokyo, the temperature of the Pacific Ocean suddenly increases and causes the largest typhoon ever seen in Japan to head towards Tokyo with devastating force. The tidal wave generated by the typhoon covers the coastal city area with water. The Tokyo Fire Department dispatches its elite rescue unit, Hyper Rescue, and their sonar picks up a signal from underwater. Beneath the ground, in one devastated subway station, there is someone sending out a code which is known to rescuers only: 252 252 "We have survivors!" A rescue party tries to save the survivors at the risk of their own lives. In the face of death, a daring rescue operation is to be carried out.
The Kumagawa Hospital which is located in the outskirts of town. Ogami Runa joined as a nursing staff 2 weeks ago. One night, with the lights all turned low, her fellow colleague, Suzuki Ayako is terrified out of her wits when a woman dressed in a school uniform (sailor) with blood dripping all over her, appears before her. A few days later, Runa's childhood friend, Sakai Manami who works at a movie production company, calls her out for a meet-up. Ever since she was a child, when she saw the ghost of her dead schoolmate, Runa realises that she could sense and see the ghosts around her. Bullied by her other classmates, Manami is the only one who had befriended her. Due to her ability, Runa always tries to ignore talks of ghosts sightings by other nurses and patients. Amidst all these, the medical intern Kumagawa Asahi, whose father owns the hospital, has a strange fascination with the mysterious old hospital wing's top floor. One night, Runa goes to the old hospital wing to fetch some supplies, and she hears a voice calling out her name. Entranced, Runa follows the sound and goes up to the top floor. She bumps into the wall at the end of the corridor, and the sound seems to come from within. Perplexed, Runa stands there contemplating the wall, when all of a sudden, a door appears before her eyes... ~ TBS
he film opens with the Republic of Singapore apparently being under an immense invasion from a fictional army, with iconic Singaporean landmarks (such as the Merlion and the Esplanade) coming under fire and many civilians killed brutally. It is later revealed that the war was fictitious setting of a war-based role-playing game played by Ken Chow (Joshua Tan), a rich and spoiled child reluctant to enlist into National Service. Ken plans to study abroad with his girlfriend Amy (Bong Qiu Ting), but his plans are derailed by NS. After being chided by Amy for his childishness, Ken takes it out on a nearby rubbish bin, to be apprehended by two policemen in the vicinity. A disappointed and embarrassed Amy looked very sad and angry.
Back home, after being driven back by his father (Richard Low), Ken confides to his parents about his fears of National Service. His overprotective mother (Irene Ang) decides to help him think of ways to defer, but to no avail. Eventually, they are all forced to face the hard truth - there is no going against the law. The Chow family sadly send off Ken on the day of his enlisting. Thereafter, Ken and a few other recruits are assigned to Ninja Company (Platoon 2, Section 2) and are sent to their bunk and introduced to their Platoon Sergeant (Tosh Zhang), a portrayal of the tough-nails sergeant stereotype. Whilst waiting for the mandatory haircut, Ken gets to know a few people - "Lobang" (Wang Wei Liang), Aloysius Jin Sia-lan (Maxi Lim) and "I.P. Man" (Noah Yap).
After two weeks of training, Ken and the other recruits are allowed to book out. A lavish party is thrown to celebrate Ken's return, but his mood is ruined when he is shown a photo of his girlfriend with another man. Ken angrily confronts her and demands that they meet, which she does not agree to. She later admits that she has fallen for another man and dumps Ken on the highway. Determined to regain her love, Ken devises a plan to escape from Pulau Tekong and send her off, for he feels she is merely just testing him. Ken stops drinking water, in hopes to get a heat injury, for which he would be sent home for ten days; he takes the extra measure of sleeping under a ceiling-fan after dousing himself in cold water. However, he gets into a situation worse than expected and he is quickly sent off to a hospital after collapsing during training. Ken's father is alerted of his son's critical condition while in a company meeting. He quickly drives off to the hospital, but the shock and strain is too much and he suffers a stroke while driving and violently collides with another vehicle.
Ken wakes up in the next scene, surrounded by his two sisters, in a hospital. He realised his foolish actions have caused problems for many people and cannot bear to face his father, who has survived the car crash and is recuperating in another ward in the same hospital. Awakened to reality, Ken is finally fit enough to go back to training. The film ends at this junction, and snippets of the next part are shown.
