The job: a delivery, no questions asked. The problem: curiosity is a deadly sin.
A smuggler gets work based on reputation. When an old employer refers the Mobius for a job, it looks like a big payday. A simple pickup and delivery. No questions asked; no looking inside the cargo. All it requires is a fast, stealthy ship and a crew who can keep their imaginations and consciences in check until the drop-off. The Mobius is up to the task, but when the crew can't live up to their end, they're faced with a moral dilemma. Do they cut their losses? Contact the authorities? Take the money and run?
Or do they get talked into the stupidest, most reckless, and least profitable course of action they could possibly take? Doing the right thing.
