A sweet, wallflower who works at a bank is courted by a Lothario bank robber who informs her that his crew is robbing her bank. Her love for him is to motivate her to assist them with key knowledge they need for the bank safe. On the day of the robbery, with a change of mind, she pushes the silent alarm which is seen by her lover, sealing her fate. When the same bank is robbed by similarly masked gunman again, it looks like the bank was struck twice by the same robbers, though years apart. The team is convinced there must have been an 'inside man'.
