Daniel Rigmaiden- a brilliant, young scam artist turned whistleblower-evades the FBI for months after being accused of filing fraudulent tax claims and illegally collecting hundreds of thousands of dollars from the IRS. After being tracked down and arrested by the feds, Daniel becomes convinced his location was identified through illicit means. He uses his time, then in prison, to investigate. His obsessive search for the truth leads to a groundbreaking discovery: law enforcement used a secret technology called a Stingray to intercept his phone calls and personal information, as well as those of millions of unsuspecting Americans. He takes his discovery public, and the revelation not only carries implications for his case, but also for the fate of the Fourth Amendment.
