Investment Banker Gregory McGregor is still in love with his ex-girlfriend, but she's engaged to be married. The woman he is currently dating is a nymphomaniac in love with his money but he's the only person who can't see it. His only other love is the career for which he prepared so diligently, but the blue-chip investment banking firm for which he works has a sordid history. On the rebound from a long period of joblessness and a bad relationship, his mind is clouded. When Greg's friends question the connection between the death of an accountant and the arrest of a high school honor student, Greg shrugs it off as insignificant. Immediately after the accountant's demise, a homeless man is seen leaving the area, which Greg's friends also question. Raising questions, however, is dangerous, as whoever raises them has a fatal accident in the vortex of The Nightingale Call.
