This is a doomsday rebirth short drama. A pair of twin sisters were betrayed by their patriarchal mother and uncle in their previous life, and finally drowned in the raging flood, dying with hatred. Blessed by fate, the two were reborn thirty days before the arrival of the doomsday rainstorm. With the painful memories of their previous life, the sisters resolutely abandoned their ten-million-yuan river-view villa and exchanged it for an abandoned weather station on the mountain top. They then sold all their assets and did their best to transform this weather station at an altitude of 1,000 meters into an impenetrable cloudtop fortress, frantically hoarding a large amount of survival supplies and defensive weapons, just to resist the doomsday crisis and the intrusion of villains. The doomsday came as scheduled, with torrential rains and overwhelming floods. Greedy and insatiable, their mother and uncle's family repeatedly colluded with bandits to besiege the cloudtop fortress, trying to seize supplies and occupy the fortress. The sisters, who could no longer bear it, stopped showing mercy. With the solid fortress and adequate preparations, they fought back fiercely and finally killed all the villains, making the betrayers reap what they sowed. Since then, the sisters have depended on each other in the cloudtop fortress and safely survived the doomsday.
