Rachel, a young woman in serious debt, needs to find a job fast before she’s made homeless. She gets a lucky break when she is offered a great position in a successful company.

Soon her new job becomes a living nightmare. Rachel desperately wants out but she has no other way of escaping her debts. She’s trapped. Then she makes a shocking discovery.
