Dave Paulides investigates cases of elk hunters who've gone missing from specific regions of North America, and explores the theory that there could be a connection between these disappearances and sightings of UFOs. This project brings together top officials from the FBI, local law enforcement, search team members and others that describe a spell-binding fact trail that will leave the viewer asking more questions than officials are willing to answer.

The series follows the tragedy that occurred when terrorists attacked at the annual Boston Marathon on April 15, 2013. They carried out the attack by placing two homemade pressure cooker bombs which detonated near the finish line of the race 14 seconds and 210 yards (190 m) apart. That resulted in three fatalities and hundreds injured, including 17 who lost limbs. With the help of archive footage, interviews with investigators, witnesses, survivors, and occasional reenactments, it offers details about the FBI investigation into what was quickly deemed a domestic terrorist attack.
In the first episode, hours after the blasts, investigators pore over evidence. One photo and a few seconds of footage lead to a breakthrough - and an agonizing choice.

The series showcases what happened in 1993 in Waco, Texas when cult leader David Koresh faced off against the federal government in a siege of 51 days. In the first episode, gunfire erupts when federal agents arrive at the Branch Davidian compound with a search warrant. Hostage negotiators later attempt to get the children out of the compound.
David Koresh was a member and later a leader of the Branch Davidians, a religious sect and offshoot of the Davidian Seventh-day Adventists, a movement based at the Mount Carmel Center outside Waco, Texas. His apocalyptic Biblical teachings attracted various followers. He became subject to allegations about polygamy and child sexual abuse by former Branch Davidian associates, although investigation by authorities found no conclusive evidence. Further allegations related to the Branch Davidians' stockpiling of weapons led the FBI to launch a raid on the group's Mount Carmel compound in February 1993.

Told from both sides of the law, this documentary series follows the FBI's battle to bring down infamous mob boss John Gotti, widely regarded as one of the most dangerous figures in the history of organized crime. Through the testimonies of journalists, real-life personalities who helped take down him, and even former mobsters, the showrunners tell the tale of Gotti’s rise to prominence and his subsequent downfall. The film features archival footage, audio tapes and exclusive interviews.
In the first chapter, when Paul Castellano, the head of the Gambino crime family, is murdered on a busy street, there's only one suspect: his former protégé John Gotti.

In the final episode, we hear how employees on the 17th floor were rewarded, and we see Madoff's $65 billion Ponzi scheme quickly collapses as investors begin to withdraw their money during the 2008 Financial Crisis. We see how Madoff's sons attempt to stop their father from writing bonus cheques for long-time investors, faithful employees, and extended family to help cushion the blow. Madoff confesses to the Ponzi scheme, and the FBI arrests him.
After pleading guilty, Madoff is sentenced to 150 years in prison. Two years after learning of the Ponzi scheme, his eldest son Mark is found hanging from a pipe, dead of an apparent suicide. His other son dies of lymphoma six years later.

Following their identification, the Tsarnaev brothers killed an MIT policeman, then kidnapped a man in his car. They had a shootout with the police in nearby Watertown, during which two officers were severely injured (one of whom, Dennis Simmonds, died a year later). Tamerlan was shot several times, and his brother Dzhokhar ran him over while escaping in the stolen car. Tamerlan died soon after.
An unprecedented manhunt for Dzhokhar ensued, with thousands of law enforcement officers searching a 20-block area of Watertown. Residents of Watertown and surrounding communities were asked to stay indoors, and the transportation system and most businesses and public places closed. After a Watertown resident discovered him hiding in a boat in his backyard, Dzhokhar Tsarnaev is cornered into an intense standoff. As officials navigate remaining questions and suspicions, the city emerges Boston Strong.
