The script depicts a man sitting on a pier who witnesses another man walk by and commit suicide by shooting himself in the head. The sitting man shows no reaction and calmly writes something down before leaving. It is then revealed that the two men seen were actually the same person, implying it was all staged or not real.

1. Triggered Productions - Final Script
SOUTHBANK PIER - MIDDAY
We see various establishing shots and mid shots of London and its
people, some looking happy and some in a rush however they are all
going about their daily lives, looking happy and everything appears
tranquil.
SOUTHBANK PIER – MIDDAY
We see a man sitting down reading a newspaper on a bench on a pier.
It is quiet, almost eerie and is appears as nothing is happening.
SOUTHBANK PIER – MIDDAY
The same man is sitting down reading the newspaper in the exact same
position. Another man then walks past him in haste, the man sitting
acknowledges the man who walks past however the man who walks past
does not acknowledge the man sitting down. There is no reaction
between the two and ultimately no reaction in the scene. The man who
is walking continues until he reaches the edge of the River Thames.
He then stops and do not move. The man then agonisingly slowly pulls
a gun from his pocket and raises it to his head. He then pulls the
trigger.
The man at the beginning sitting down with the newspaper does not
flinch, he just puts down his newspaper and takes a notepad out of
his briefcase and writes something down in a foreign script and puts
the notepad back in his briefcase. He then stands up from the bench
and his face is revealed to the audience. He leaves in the opposite
direction of the incident that has just taken place and walks to
into a crowd and the audience is shown this from a long shot as he
disappears into the crowd. Then there is a scene of the man who has
shot himself, however it is just of his hand and the gun. Then the
camera closely pans past the man’s face and his face is revealed to
the audience. The audience has now seen both of the characters faces
and it is revealed that they are the same person.
