In Tokyo, Japan, there lives in the Suzuki family of four, and his father, Yoshiyuki Suzuki (Fumiyoshi Koichi), is a company employee, selfish and face-loving, and basically does not worry about anything other than work. Her mother, Mitsue Suzuki (Eiri Fukatsu), is a full-time housewife who worries about the family's diet and life, but is always disliked and complained by her husband and children. The taciturn older brother Kenji (Yuki Izumizawa) is a taciturn college student, and the younger sister Yui Suzuki (Aoi Wakasa) is a socially addicted and somewhat selfish high school student.
The peaceful life was shattered by a major blackout disaster, at first, people thought it was a small, temporary blackout, and did not take it seriously, but later found that the tram stopped, the car could not catch fire, as long as it was related to electricity, it could not be used. People realized the seriousness of the matter.
Because there is no electricity, there is no way to cook food, fast food has become the only choice, the supermarket can only use cash to check out, fortunately, the mother Guanghui usually has cash in reserve, the family eats around the candlelight at night, and after dinner they also look at the stars together, usually they all play each other, at this moment, but there is a rare warmth.
But soon, things started to get out of hand. Food and water are scarce, supermarkets have been emptied, and people are panicked. There was no reason for the blackout, and people began to flee the city.
The death of the upstairs residents of the community due to food shortages strengthened the Suzuki family's determination to flee the city, and they decided to go to Kagoshima, where Mitsuhye's mother's family could at least live a self-sufficient life.
The family had a bicycle, with clothes and a few bottles of water road left, they decided to ride a bicycle to Haneda to catch a plane, the road is full of people running away, most of them are on foot, after the power outage, buying a bicycle is also a luxury.
There are water sellers on the road, the price is very high, how can the stingy father buy, but the farther away, the price of water is getting higher and higher, several bottles of water are quickly drunk, there is no way but to stop buying water, the price of water has been several times the original, fortunately the mother will bargain, bought a lot of water, because the road is still very far, the water behind is definitely more and more expensive.
The family rushed to the airport, even knowing that the plane had been grounded because there was no electricity. The family had to stay in a hotel without water at a high price, and my father made a decision to ride to Kagoshima.
The next day, brother Kenji and sister Yui went out to find maps and food, the supermarket on the street had been abandoned, the map had long been taken out, fortunately Kenji found a map of children's books, although not accurate, at least can see the general route, roughly calculated, at least it takes more than a month to arrive.
Money can no longer buy things, and food can only be exchanged through food. GuangHui exchanged some rice with the water and wine she carried with her, the family went on the road again, the map of the children's book could not find the right way, Dad took the family to go wrong, helplessly they went on the elevated shelf, only to find that the elevated shelf was full of fleeing people.
While resting on the road, they met a couple who asked the family of four if there was any extra water to sell them, but Mom, who was going to cook something to eat, heard these words and quickly put away the gas stove, and Dad also put his clothes on their excess mineral water.
When the water was all drunk, Dad insisted on drinking the stream despite the advice of his family, but squatted in the grass and diarrhea the next day in the storm. The only food left was also destroyed by the rain, Kenji and his sister found an abandoned supermarket to find pet cans and distilled water for the car to fill their hunger, Kenji also found a signal bomb to use to make a fire, and his arrogant father had to drill wood to make a fire but could not make a fire.
Moving on, they encounter a group of wild survival masters who are comfortable without electricity, which makes the wretched Suzuki family envious. The group was very enthusiastic, and they introduced Guanghui to various knowledge of how to survive in the wild, how to identify wild vegetables that can be eaten; boiling and sterilizing the water that seeps from the mountains and drinking it. They took a picture of the Suzuki family with their original camera.
Father's self-righteous blind command, but never responsible for the results. The family's complaints about him accumulated as the trip continued, and finally broke out after the bullet ran out of food, perhaps it was easier to recognize himself in disaster or adversity, and Dad finally completed the growth of the role, and the family did not get the food distributed in the aquarium, and the face-saving dad knelt down and begged "Please give the two children a little food."
On the road in the wilderness, the family is exhausted, lack of water, sun, and there is no end in sight. Dad even picked up the worms in the bushes and began to eat, and at this time, Dad actually found that there was a pig on the grass in the distance, and after a long drought, the family silently surrounded it without a word, and began to chase and block the shelter in the wilderness.
Dad tried his best to finally get the pig, and the family took a knife to let no one dare to do it. Just when the family did not know what to do, there was an old man, he took the knife and directly started, it turned out that the old man was the owner of this pig, the old man raised a lot of pigs, after the power outage, the electric gate was broken, the pigs all ran, the old man was looking around for the pig.
The Suzuki family followed the old man back home, sweet well water, rich food, the Suzuki family ate very badly, the old man gave a proposal, let the Suzuki family help find the lost pigs, he provided their family with food and accommodation.
The Suzuki family began to find pigs, kill pigs, pickle, smoke life, from the beginning of the fear of clumsiness, slowly everyone can skillfully do their own work, the pigs are finally packed, and the Suzuki family also decided to leave, Mitsue is also worried about her father who is far away in Kagoshima, the old man brought enough food, and the family got back on the road.
A river blocked the way, the family stopped complaining, worked together to make a raft, first sent my mother and sister to the other side, came back to transport vehicles suddenly rained heavily, the father was washed away, only to find the father's lost wig downstream.
Determined that his father had died, he endured grief, the mother and daughter three returned to the road, the wild dogs grabbed food, and the mother fell down the hillside, and her leg was broken. Desperate, I encountered a train, an old-fashioned steam train, and in the absence of electricity, the old-fashioned train was put back on duty, and the mother and daughter trio were finally saved.
The father who was washed downstream did not expect to be dead, he stumbled all the way, the strength was not much, paralyzed sitting on the ground to see the train coming in the distance, he had no strength to shout, he remembered the signal bomb found by his son, the white smoke from the signal bomb was found by the mother, and the father was saved. The family watched each other become calm and intimate.
At the end of the film, the family came to Kagoshima and began a life of fishing and weaving, and the family accompanied grandpa, ploughing at sunrise, resting at sunset, self-sufficiency, and integration into local life.
