When a deadly virus sweeps the country, Vivian Thomas sets out for California in hopes of seeing the daughter she gave up for adoption. Then her car breaks down and she's faced with a choice. Give up, or accept a ride from redneck brothers, Angus and Axl, but she's prepared to do whatever it takes to reach her daughter.

When the dead start coming back, Vivian has to figure out how to be a mother under the most frightening circumstances, cope with Angus's aggressive mood swings, and sort out her growing attraction to his brooding younger brother, Axl.

Trusting him means going into the middle of the Mojave Desert and possibly risking their lives, but with the streets overrun and nowhere else to turn, it seems he might be their only chance for survival...
