Four years after his wife Becca's death from cancer, businessman Karsh has invented "GraveTech", a tombstone that broadcasts a live, interactive 3D image of the deceased's decomposing corpse. The image is created by a modified
shroud, and Karsh plans to be buried with Becca when he dies. Though unable to find new love, he maintains a close friendship with Becca's identical sister, Terry. He dreams of Becca returning from the man who treated her, her lover, Dr. Jerry Eckler, each time increasingly weak and dismembered. Several tombstones in the GraveTech cemetery including Becca's are destroyed, and the technology's network is
encrypted by hackers, leaving the shrouds unviewable. Terry's ex-husband, Maury, who coded GraveTech's security and created a
virtual assistant in Becca's image for Karsh named Hunny, determines the hack originated in
Iceland, one of the countries where Karsh plans to expand his business. Viewing screenshots of Becca's corpse, Maury notices strange protrusions on the bones that Karsh believes were caused by her cancer. At the same time, Karsh is accosted by Soo-Min, the blind wife of a CEO who wants to sponsor a GraveTech in
Budapest. He begins sleeping with her. Karsh's relationship with Terry turns sexual, with Terry aroused by Karsh's description of sex with Soo-Min and his growing fascination with the conspiracy around GraveTech. As Karsh learns that the hack did not come from Iceland, Maury notices that the destroyed tombstones had their data lines bugged. Soo-Min warns Karsh that Hunny's code was found to be unstable, and the AI takes on Becca's naked, dismembered form as it taunts Karsh about his supposed sexual inferiority to Eckler. Terry shows him a video she covertly took of Maury, whose jealousy of Karsh's relationship with her has caused his schizophrenia to resurface. In the video, he claims to be in full control of Hunny and implies that he was in some way behind the attack on GraveTech. After being called to talk, Karsh meets Maury in the woods, who shows him the bloody remains of his hand after losing two fingers. He claims that he hired a pair of
Russian hackers to take over GraveTech's network, which convinced a group working under the
CPC, investors in GraveTech who supposedly tapped the data lines, that he could be used as a mole. They tortured him for info on the Russian "operation". Terry later claims that he lost the fingers in high school and hides them from everyone. While GraveTech's network is brought back online and the tombstones are repaired, a doctor examining the protrusions on Becca's body informs Karsh that they are artificial. Karsh is shocked to find Eckler's murdered body buried in his spot next to Becca. Terry theorizes about what could have happened to put Eckler there, and when Karsh pretends he hired a hitman to kill and bury Eckler, she becomes aroused. Believing that Becca now has someone to keep her company in death, Karsh willingly gives up his spot and goes with Soo-Min on a jet to Budapest. As they kiss, she suddenly appears to him with identical scars to Becca and, speaking in her voice, offers to be buried with him in Budapest, which he accepts. ==Cast==
