The only favor the aliens do for Clint Beecham when they abduct him is give him a shirt that says DO NOT EAT on it in their language. He's told that as a physicist, he is to be reserved, along with five other scientists, for a mysterious purpose.

But fifty thousand other humans on board the interstellar scout ship are scheduled to be butchered and frozen, a food supply for the long journey to the alien homeworld. Clint and the other Reserves can't stand by and let that happen.

If they don't find a way to stop the ravenous aliens from reporting that they've found a planet full of delicious creatures to eat, the fifty thousand humans on board will only be the first of billions: the entire earth will become an all-you-can-eat buffet.
