In a world recently ravaged by plague, survivors ration their miles traveled and attempt to survive scorching daily temperatures. One Sunday during testimony meeting, a woman stands and begins speaking in tongues. When Mary finds she understands, she interprets for the rest of the congregation. Each month the woman speaks, and each month another woman interprets. After several months, Mary is again the one to understand the words, and she announces it is time to gather in preparation for the Second Coming.
