It was the seventies and the seventies were in the future.
A powerful device was invented and two competing companies wanted it.
One of them was owned by an alien. The name of the company was something like Evencalibur.
The inventor wanted to sell them his or her patent but was too eager therefore selling it for too little.
Which made the new owner laugh about it to his assistant who was dressed in white and and looked very much like the partner of his competitor who was dressed in black.
The patent was stored in an old folder which contained dozens of notes and other papers. All signed at the bottom left corner with the date top right in pencil.
He knew he was lucky to have it on paper because all electronic files were lost. When he took it out to have it signed by himself and his assistant and have both their picture taken as evidence that the patent was now his, she tried to kill him. Or was it the wife of his competitor? Anyhow, he was lying on his back when he managed to get hold of a knife and lunged it over his left shoulder, stabbing her in the chest.
Trying to say something she fell to the floor and he used the invention on himself, getting ready for a press conference. Looking in the mirror he got stared at by a younger version of himself and ran to his study where there was a child who was also his brother/friend/business partner and who told him: "That is the wig my father gave me!"
