Walls of Jericho

S1 E4: When Jake and Heather find a stranger on the side of the road who is sick and disfigured from radiation poisoning, they must decide whether to help him and risk contamination or do nothing and allow him to die. After they decide to help the stranger and take him to the hospital, Jake and Hawkins sit vigil in hopes that he will be able to give them information about what's going on outside of Jericho. Meanwhile, when the generator at the hospital is low on gas and supplies in town begin to dwindle, the police must ask disgruntled and panicked townspeople to siphon gas from their cars.
