Underlings - 1. The Bottleneck

An ongoing sci-fi series:
A man disappears in an airport and re-appears just days later having aged by 30 years...
Landry hears of drugs being peddled to make people subordinate, abductions, possible time travel.
When a planet invades itself, only a wafer thin resistance remains to fight on.
Who are the Underlings?
We are.
