Cameron has built a good life for himself despite his rough start. He can't trust enough for romance, but he's okay with that. He's got good money coming in as a graphic designer and just inherited a duplex in Plymouth from his estranged grandfather, so he doesn't have to worry about keeping a roof over his head. He likes his tenants, he has friends, and he's content with that.
When two guys claiming to be paranormal investigators show up on his doorstep tell him the tenants contacted them about "phenomena" in the house, he knows they're con men right away. For one thing, they claim he was the tenant. He sends them packing. It doesn't matter that one of the con artists is the hottest guy Cameron has seen in years -- if anything, that just makes Cameron more suspicious.
Then things go wrong in the house, things he can't shrug off or ignore. The past Cameron has worked so hard to leave behind is coming for him, and it's angry.
