A simple girl has a very bad day as her shining career moment has turned into her worst nightmare. Close friends turn their back on her, her boss threatens her career and dismisses her for the weekend to think about her next steps. On her ride home on the train, a mysterious yet overtly polite man befriends her before hand cuffing a stainless steal brief case to her, passing her some instructions and an address before slipping away out of sight. If she thought she was having a bad day before, now she has to deliver the case before the timer counts to zero and triggers a bomb. Why her? Why today?
