Survivors (1975)

S3E4 Mad Dog

Charles sets out on his own in search of Tom Walter but soon finds himself in a perilous situation with a pack of aggressive dogs. Just when things seem dire, he is saved by a man named Fenton, who accompanies him back to the halfway house. The following morning, Charles learns that Fenton has come down with rabies. After securing Fenton, Charles heads to a nearby village for assistance. He returns with two men, Sanders and Jim, but they are ambushed by Fenton, forcing Charles to kill him. Fearing that Charles might also be infected, the men turn on him, prompting Charles to flee into the wilderness as a manhunt ensues.
