After a mysterious disease kills every resident over 22 years old, survivors of a small town called Pretty Lake must fend for themselves when the government quarantines them. The series explores the power vacuum that results from the situation; the desire of the inhabitants to escape without any care of the consequences of their actions and the effect of hormonal, young-adult angst becoming the guiding force for an entire community
Given the decimation of all authority figures, what would you do? Sulk in your room for days? Steal that car you always wanted? Use a gun on all the undesirables below your class station? The most genuinely upsetting moment in the first two installments comes when a preadolescent boy whose parents have died gets behind the wheel of a car and accidentally kills the older brother of another youngster. For some reason, this throwaway scene gives a palpable sense of a world off its axis.

The main draw...should be the presence of former “iCarly” co-star Jennette McCurdy as one of the survivors in the small town of Pretty Lake, where the over-21 population is being decimated by a strange outbreak, and everyone else has been quarantined.
