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. Vivian knows the offer has more to do with her double D's than kindness, but she's prepared to do whatever it takes to reach her daughter. The virus is spreading, and by the time the group makes it to California, most of the population has been wiped out. When the dead start coming back, Vivian and the others realize that no electricity or running water are the least of their concerns. Now 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. While searching for a safe place to go, they pick up a pompous billionaire who may be the answer to all their problems. 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.
