A pair of plumbers moonlight as ghostbusters for clients who report paranormal phenomena. Jason Hawes and Grant Wilson founded TAPS, the Atlantic Paranormal Society, in 1990 as an extension of their interest in the paranormal, and since that time they have made it their life's work -- when they're not unclogging drains, that is -- to help individuals or groups throughout the country who feel they have been affected by seemingly unexplained disturbances. Grant left TAPS and the show in 2012, leaving Jason as the team's lead investigator.

Cosplay -- the practice of dressing up as characters from movies, books or video games -- is a popular activity in the sci-fi community. People transform themselves into pop culture-inspired creations, often with an emphasis on anime characters. Usually, it's just for fun and playful contests, but on "Cosplay Melee," the perfect costume can be worth $10,000 to a cosplayer. Each episode sees four contestants creating full costumes and character origin stories, then hitting the runway in an attempt to impress the judges, who are world-class cosplayer LeeAnna Vamp and costume creator Christian Beckman, by looking -- and acting -- the part. Whoever the judges feel most embodies the character is proclaimed the winner and earns the grand prize. Actress Yvette Nicole Brown ("Community") hosts the show that Syfy says compares to reality show "Face Off" but "with a triple dose of adrenaline."

Aspiring artists compete to bring their wildest beast to life.

People often think that ghosts and other spirits live in and "haunt" buildings. But people don't usually think the same thing about objects like paintings, jewelry and dolls. But the Zaffis family, led by dad John, not only thinks that ghosts can inhabit such objects, they collect what they think are paranormal objects. John Zaffis is a paranormal investigator who has been asked to consult on hauntings for nearly four decades. Through the years, he has amassed thousands of possessed objects that he keeps in his bizarre museum, where visitors report feeling an evil presence upon entering the building. Assisting John on his investigations are his children, Chris and Aimee. Also along for the (potentially scary) ride are tech specialist Brian Cano, who has been fascinated by the paranormal since he was young, and an additional psychic investigator or two.
