[citation needed] Fear Nothing, told in the first person, follows 24 hours of Christopher Snow's life, as he discovers and attempts to unravel a mysterious and seemingly endless conspiracy centered on a military compound called Fort Wyvern.

Later, upon returning home, Christopher finds his father's gun on his bed, and an urgent message on his answering machine to call Angela Ferryman, a nurse and lifelong family friend.

Christopher sets off on his bicycle (with Orson following) to the home of his best friend Bobby Halloway, a surfer who lives in a cottage on the edge of town, near to the sea.

The message sends him and Orson off on a race into the mist of the night, where they are followed by a group of mutated rhesus monkeys which are led by a shadowy figure of a half-man, half-beast.

Frost hints at unusual, uncommonly intelligent animals escaping from the military base, including cats and dogs.
