Roman began stalking Maureen and filming her relationships with other men including Hank Loomis.
He used this footage to reveal to Billy why his mother had "abandoned" him before convincing him to kill Maureen, sparking the chain of events in Scream and Scream 2.
After the murder spree begins, Sidney Prescott (Neve Campbell) begins receiving taunting and threatening phone calls from Ghostface, who claims knowledge of her mother Maureen Prescott (Lynn Mc Ree)'s brutal murder, one year prior to the events of the film, a murder that was blamed on Cotton Weary (Liev Schreiber).
The Ghostface disguise allows suspicion to fall on many people, including Sidney's boyfriend, Billy Loomis (Skeet Ulrich), her father, Neil Prescott (Lawrence Hecht), her friend, Randy Meeks (Jamie Kennedy), and her schoolmate, Stu Macher (Matthew Lillard).
Ghostface is revealed in the finale as both Billy and Stu, who reveal that they murdered Sidney's mother and framed Cotton.
Billy cites his motivation as abandonment by his mother (Laurie Metcalf), brought about by his father's affair with Maureen, while Stu cites "peer pressure".
The character is primarily mute but voiced by Roger L. The character first appeared in Scream (1996) as a disguise used by teenagers Billy Loomis (Skeet Ulrich) and Stu Macher (Matthew Lillard), during their killing spree in the fictional town of Woodsboro.
Ghostface is revealed as Sidney's half-brother Roman Bridger (Scott Foley), born to their mother Maureen during a two-year period when she moved to Hollywood to become an actress under the name Rina Reynolds.
After being gang-raped and impregnated at a party, she gave Roman up for adoption who sought her out years later, only to be rejected, denying she had ever been Rina.
The Ghostface disguise allows suspicion to fall on several characters, including Cotton, again, and Sidney's boyfriend Derek (Jerry O'Connell).
However, Mickey (Timothy Olyphant), a friend of Derek, reveals himself as the killer, seeking fame for his prolific exploits.
