A strange disease kills off some of the richest and most influential people on the planet. First it was the billionaires, then the multi-millionaires and so on progressively... Then it threatens to strike anyone with any sort of fortune. With the whole world panicking, people try to flood the market with assets the world no longer wants.

Ángela Vidal, the young television reporter who entered the building with the firemen, manages to make it out alive. But what the soldiers don't know is that she carries the seed of the strange infection. She is to be taken to a provisional quarantine facility, a high-security installation where she will have to stay in isolation for several days. An old oil tanker, miles off shore and surrounded by water on all sides, has been especially equipped for the quarantine.

After a mysterious leader imposes his law in a brutal system of vertical cells, a new arrival battles against a dubious food distribution method.

A slab of food descends down a vertical facility. The residents above eat heartily, leaving those below starving and desperate. A rebellion is imminent.
