The sources only offer a basic plot summary--a struggling actress, Dana Tilly, is hired to impersonate a businessman's wife at a reception, and her life is soon in danger--but do not provide detailed scene-by-scene breakdowns, character interactions, dialogue, deaths, twists, or a full resolution.

Otherwise, based on the current information, here is the most detailed linear narrative possible:

Opening: Dana Tilly's Struggle

It's a rainy evening in Vancouver, late October 2013. Dana Tilly, a talented but underemployed actress, sits in her modest apartment, scrolling through casting calls on her laptop. The rent is due, and her agent's last message was a polite "nothing this week." Her phone rings--an unknown number. A smooth, professional voice offers her a one-night gig: impersonate a woman at a high-stakes business reception. The pay is exceptional. "It's just acting," the voice assures her. "No lines, just be there, smile, make small talk. Discretion is key." Dana hesitates, but desperation wins. She accepts.

Arrival at the Thomas Residence

The next evening, Dana arrives at the sprawling Thomas estate in an upscale neighborhood. She's greeted by Mark Thomas, a handsome, confident businessman with a practiced smile. He briefs her quickly: "You're Leesa tonight. My wife is… unavailable. Just follow my lead. No one will suspect a thing." Dana notices tension in his jaw, a flicker of something darker behind his eyes, but she pushes her doubts aside. She's given a dress, a wig, and a few details about "Leesa's" life. The house is opulent but strangely empty, save for a few staff members who glance at her with curiosity.

The Reception: Impersonation and Unease

Guests arrive--business associates, investors, a few local dignitaries. Dana, as Leesa, circulates, making polite conversation. She catches snippets of whispered conversations, hears Mark's name mentioned with a mix of admiration and wariness. A woman named Isabel Johnson watches her closely, a knowing smirk playing on her lips. Dana feels a prickle of paranoia. "You're doing great," Mark murmurs in her ear, but his grip on her arm is a little too tight.

Midway through the evening, Dana excuses herself to the restroom. In the hallway, she overhears Mark arguing with a man named Sal. "It has to be tonight," Mark hisses. "No mistakes." Dana's heart races. She returns to the party, but now every smile feels forced, every glance suspicious.

The First Revelation: A Dangerous Game

As the reception winds down, Dana is cornered by Isabel, who leans in close. "You're not Leesa," she whispers. "But you already know that, don't you?" Dana's pulse spikes. Isabel slips her a note: "Meet me in the garden. Now." Outside, under the dim glow of string lights, Isabel reveals the truth: Leesa is missing. Mark is desperate to cover it up--his business deal depends on his wife's presence. "But there's more," Isabel says. "Leesa wasn't just absent. She was in trouble. And now, so are you."

Before Dana can respond, a shadow moves in the bushes. Isabel is suddenly pulled away, a hand clamped over her mouth. Dana stifles a scream and ducks behind a hedge. She watches, horrified, as Isabel struggles, then goes limp. A figure--tall, broad-shouldered--drags her body into the darkness. Dana's hands tremble as she realizes: she's in real danger.

The Investigation Begins: Detective Ronald Billins

The next morning, Detective Ronald Billins arrives at the Thomas residence. Mark reports Isabel missing, playing the concerned host. Dana, shaken but determined to survive, plays along, but Billins is sharp. He notices Dana's nervousness, the slight inconsistencies in her story. "You're not who you say you are," he murmurs to her when Mark is out of earshot. Dana's eyes well with tears. "I was just hired to pretend. I didn't know… I didn't know anyone would get hurt."

Billins takes her aside, promising protection if she helps him uncover the truth. Together, they begin to piece together the puzzle: Mark's business is failing, his investors are pulling out, and Leesa's disappearance is at the center of it all. But who is really pulling the strings?

The Second Death: Unmasking the Killer

That night, Dana returns to her apartment, but she's not alone. A figure waits in the shadows--Wallace River, Mark's right-hand man. He confronts her, his voice cold. "You saw too much." Dana backs away, but Wallace is faster. He lunges, but Dana fights back, grabbing a lamp and striking him. He stumbles, falls, hits his head on the edge of a table. He doesn't get up. Dana stares at his lifeless body, her breath coming in ragged gasps. She calls Billins, her voice shaking. "I didn't mean to… he attacked me." Billins arrives quickly, surveys the scene. "You did what you had to," he says. "But this isn't over."

The Final Confrontation: Mark's Downfall

With Wallace dead, the net tightens around Mark. Billins and his partner, Detective Maitland, bring him in for questioning. At first, Mark is smug, confident in his alibi. But Dana, now safe in police custody, provides the final piece: a recording she made on her phone during the reception, capturing Mark's conversation with Sal. "It has to be tonight. No mistakes." The implication is clear: Mark orchestrated Leesa's disappearance, and Isabel's murder was a cover-up.

Confronted with the evidence, Mark's facade crumbles. "It was all Leesa's idea," he snarls, trying to shift blame. "She was going to leave me, take everything. I had to stop her." But the detectives aren't buying it. "You're under arrest," Billins says, cuffing Mark. "You'll have plenty of time to explain yourself."

The Resolution: Dana's Future

In the aftermath, Dana is exonerated. The real Leesa's fate remains unknown, but the police continue their search. Dana, though traumatized, finds a strange sense of closure. She visits Billins at the station one last time. "Thank you," she says. "For believing me." He smiles faintly. "You're tougher than you look." As she walks out into the sunlight, Dana takes a deep breath. The nightmare is over. She's alive. And maybe, just maybe, she's ready for her next role--on her own terms.

Deaths and Culprits - Isabel Johnson: Killed by an unknown assailant (implied to be acting on Mark's orders) during the reception. - Wallace River: Killed by Dana Tilly in self-defense during a confrontation in her apartment.

Major Plot Twists and Revelations - Dana's impersonation is part of a cover-up for Leesa's disappearance, orchestrated by Mark. - Isabel's murder reveals the depth of the conspiracy and the danger Dana is in. - Wallace's attack on Dana exposes Mark's desperation to silence witnesses. - Mark's arrest is the culmination of the investigation, revealing his role in the crimes.

Character Secrets - Mark Thomas is not just a businessman in trouble--he's willing to kill to protect his secrets. - Dana Tilly is an unwitting pawn who becomes a survivor and key witness. - Detective Ronald Billins is the moral center, determined to uncover the truth despite the risks.

Ending - Mark Thomas is arrested; his fate is left to the justice system. - Dana Tilly survives, traumatized but free, her future uncertain but hopeful. - Leesa Thomas's ultimate fate remains a mystery, a loose thread for the audience to ponder.
