Jean Robinson is someone who lays low. She buys stuff with cash, so her records don't show up. She has no family, therefor nothing to lose. So when she's recruited to what she thinks a spy organization, she hits it right off by taking care of her first victim. Then she receives more and she continues to do the same thing. But when she realizes the place she's working for isn't what she thinks it is and people aren't who they say they are; things get weird. And fast.
