Spoiler Alert: Is this Lost or Ghostbusters?

Myles(I think that's the name.) flashback (He drives up to a house while listening to the radio. Person on the radio says that it was the "worst case scenario" and a rescue mission is unlikely because of how deep it is and "all 324 passengers are confirmed dead". Myles reaches for a briefcase and goes to the front door. An African-American woman he calls Mrs. Gardner opens the door. He announces himself as Myles Strom "we'd spoken earlier" and she lets him in. The camera pans the photo of a young African-American child near the door. Must be important or someone we've seen before. "Which room is it?" Myles asks. She points upstairs. He gathers some things and says "no matter what happens or what you hear, do not come upstairs." He then says he's charging two hundred dollars instead of the one hundred dollars, because he found out from the police her grandson was murdered.

Myles goes into the room and sets down a strange device He plugs the device in and it spins. Now it gets interesting. He looks around the room and starts talking to a ghost/spirit. You can only hear Myles part of the conversation. He explains staying here is not doing his grandmother any good in fact it's causing her pain. He then says "I want to go downstairs and tell her you're gone, but first you have to show me where it is". Then there's a noise and he opens a secret compartment which has a ton of cash and some heroin in it. He takes the cash, unplugs his device and tells the ghost/spirit that he can "go now". He went downstairs and told her it worked and he's "at peace now".
