Captain Ethan Walker takes what should be an easy run to Watchtower Station in orbit above the inhabited heavy-world of Dawn. A delay in unloading their cargo forces them to layover for several days, and the station’s science director offers them the chance to visit the surface to observe the indigenous culture firsthand.
When a mistake leaves the human outpost on the surface exposed, a hunting party of superhuman Ut’aran natives capture Walker and his crew, and haul them off into the impenetrable jungle.
With the power to their life supporting exosuits dying, they must fight to survive against twice the gravity of earth while the three newest members of his crew attempt an impossible rescue mission.
Unfortunately, to escape they have to take on a cargo that puts them so far outside the law that if the Coalition catches them, the best they can hope for is death by hanging.
