When the body of Mary Shaw is found, with a camera, the recorded material does not match with Sean's when he was supposed to be on a day trip to the beach. About to be read his rights, he is suddenly released when a man shows up with a briefcase - inside are recorded tapes that prove his innocence and that the timecode on Mary's tapes were incorrect. Sean had paid him as a backup in case he was framed.
Suddenly Detective Emeric goes mental - slams him onto a mortuary table and takes that metal rotary slicing tool to his neck. Veil manages to escape, and outside the reporter Katie Carter picks him up.
As they return to his lair, she says she knows that he is innocent. Inside his hideout, they find Saul Seger alive and tied up. Katie says she found the gun that killed her mother and sisters in his house. Finally we learn that Seger found a letter from the father, who killed them all in a jealous rage before he took his own life. As his career was taking off, he didn't want to be proved wrong and so kept the blame on Sean.
Emotionally fragile, Katie turns off the cameras, and shoots Saul in the head - and then knocks out Sean. As Sean wakes, he finds himself tied up - and is then raped by Katie. She uses his finger nails to scratch her face, and plans to frame him for everything, before killing him.
There's a cut to the future where Sean has a bullet wound in his arm and is talking to Detective Mountjoy. You'll see a mysterious dead body in the background too. Sean lets on that he recorded everything secretly on the webcam -
We see that Detective Emeric breaks into the hideout, and shoots Sean in the arm. Katie shoots the Detective ... and then turns the gun on herself.
Back in the present/future again, Mountjoy slyly suggests what would happen if that footage was accidentally lost - but Sean is calm. He has another alibi - before they arrived he emailed it to the local newspaper.
As it ends, he offers his final rule and bit of advice - never stop filming yourself - ever!
