Dark dreams see the light of day in "Your Worst Nightmare," a typical Investigation Discovery true-crime series complete with jump-out-of-your-seat moments and chilling conclusions. Classic suspense film techniques highlight re-enactments of creepy, harrowing crimes, as victims' darkest dreams become unfathomable realities. Each hourlong episode features one story interlaced with commentary from law enforcement, criminal justice professionals, and psychologists, plus accounts from friends and family of the victim.

"Killer Couples" is in the same vein of the long-running true-crime series "Snapped," which tells stories of people who commit murder or attempt murder, but with a focus on couples who commit crimes. Using re-creations and firsthand accounts, each episode digs into a case, telling the story of the couple's romance, how the relationship evolved from love to manipulation, and what ultimately led the couple to commit the crime. The stories range from teenage lovers who go on a multistate crime spree to lesbian lovers who want to eliminate one of their husbands.

Each episode of this true-crime reality series examines a different felon, usually a female, who has committed murder or attempted murder. The victim is usually the perpetrator's partner. The documentary-style series features interviews with friends and family members of the accused and victims, law-enforcement officials, attorneys and other people with first-hand knowledge of the cases.

This newsmagazine investigates intriguing crime and justice cases that touch on all aspects of the human experience.

The holiday season between Thanksgiving and New Year's is often thought of as a celebratory period to spend time with friends and family. That is not always the case, though, as the period is not immune from experiencing the same types of violent crimes that occur throughout the year. This series documents stories of tragedy that struck during the holidays, with firsthand accounts from people who had friends or family members killed during the joyous time. Sometimes the victim is killed by someone close to them, such as a case of sibling rivalry turned deadly, but sometimes the killing is done by a stranger who interrupts a holiday gathering with gunfire.

Most true-crime shows let viewers know the identity of the victim right away, before working their way into revealing the identity of the perpetrator. That's not how things work on "Killision Course," which conceals all of the participants' roles until the episode's final act. While working toward the conclusion, each hourlong episode re-creates a murder case involving a victim, accomplice and killer. Stories often involve friends or lovers who commit crimes against people who once trusted them. It's all part of the road leading up to the big reveal, which is when viewers learn what role each party played in the fatal act.
