What if the key to your past lay at the South Pole?
In 2261, Sento, a beautiful, intelligent, tormented young woman, is obsessed by Isorropia, a city in Antarctica that is half-myth, half-legend. Surviving a shipwreck, Sento resolves to trek south with immigrants on a suicidal one-way journey across the melting ice. She leads the pilgrims across a raging river, weeps beneath a massive natural sculpture draped with blue ice, and defends an endangered fur seal. Meanwhile, in the secretive city, First Citizen Elita Soares watches the growing threat of the pilgrim train. She wants no more climate refugees within the city walls. When Elita learns her half-sister may be among the immigrants, she vows to stop the newcomers at all costs. Will the pilgrims reach the fabled city before Antarctica's harsh climate kills them? And why is Elita afraid of her half-sister?
