In a ruined world, based loosely on our own, the surface is haunted by terrifying and deadly masked soldiers, left behind from the wars of the past. Survivors of the 'old world' have fled to the underground. Food and water are scarce and it hasn't rained in a year. Bandi and Markus are brothers, and two of the youngsters tasked with scavenging the surface for food. The soldiers have always left the young ones alone, but things are getting desperate. Times are changing. After tragedy strikes, Bandi and Markus are alone. With only an elusive black panther to guide them, they set out in search of the sea, a sea that only Markus can remember. But they've been told the sea no longer exists and the path towards it seems impossible. It's a journey that will test their physical and spiritual selves, their beliefs and their brotherhood. As they venture on, they hope the panther that leads them is real, hope that at the end of it all they'll find safety beside the waves. But that's all they have-hope-and Death is everywhere.
