"We have dedicated our whole lives to studying the paranormal," McCarthy's character Abby Yates says in the trailer. "Now there's sightings all over the city. There are people out there who need our help."
Each new Ghostbuster has her own specialty: Kate McKinnon plays the "brilliant engineer" Jillian Holtzmann. Kristen Wiig is the quantum physics genius Erin Gilbert. Leslie Jones is Patty Tolan, the street-savvy New York expert who also owns the hearse that they transform into their epic ghostbusting vehicle, Ecto-1. And McCarthy's Yates character seems to be the one who keeps them all on track and motivated to fight spirits.
The plot is revealed too. Apparently, someone is creating a device that amplifies paranormal activity, and the ghostbusters might be the only ones who can stop it. Oh, and the ghosts can possess humans too.
"When you watch the trailer online today, if possible play it on big speakers or with a good pair of headphones," "Ghostbusters" director Paul Feig tweeted. "Crank it up, friends!"
Fans were previously treated to a 28-second teaser trailer that featured a massive police car chase, as well as SWAT teams and military forces running toward a mysterious threat. Now we finally know a little more of what that threat is including ectoplasm-spewing ghosts.
