Sienna Cole is the official crime scene photographer for the London Police. She has inherited the one-of-a-kind "Eye for Crime" from her late father Dominic Cole, a former detective with Scotland Yard’s Major Crimes Unit, enabling her to spot details at crime scenes that no one else can see.
Late one night, Sienna sneaks into an exclusive gala hosted by Blackwood Auction House, planning to secretly photograph evidence of a suspected forged artwork. Through her camera viewfinder by chance, she catches sight of a hand closing the door from the crack of the VIP room, blood oozing between its fingers. She captures footage of a locked-room murder—and the killer spots her too.
