They say you are your memories. What happens when they're not yours anymore? Detective Marr knows the rules of evidence. But when a missing person case leads him to a sealed burial site — and a man who remembers the murder without ever committing it — the rules start to break down. Across town, clinical psychiatrist Dr. Dan Levesque watches his patient speak fluent Hebrew she shouldn't know. He's seen dissociation before. This isn't it. As memories surface that don't belong, as languages, gestures, and entire histories flicker into strangers' minds, Marr and Levesque begin to uncover a pattern: people are changing. Not just mentally — but fundamentally. Something is spreading. Something no one can fully trace or contain. At the center of it: a fire, a canister, and a material designed for replication — now escaped. As paranoia grows and identity unravels, Marr must choose between the facts in front of him and the mind he no longer trusts. Because whatever this thing is, it doesn't just mimic. It crosses. Part noir mystery, part psychological thriller, and part speculative horror, Crossed is a darkly intimate exploration of memory, selfhood, and the terrifying possibility that what makes us "us" might not belong to us at all.
