Convinced the doomsday from their dream is approaching, the couple immediately gathers their entire family and frantically stockpiles provisions to change their fate. Everyone works together as one to face the crisis—no infighting, no betrayal. Even in the darkest hour, they hold fast to their humanity and kindness.
