After a scientific experiment goes horribly wrong during a demonstration, a scientist finds himself trapped in an alternate reality that bears some similarities to our own, but has some striking differences. In this other reality the Second World War had never occurred, mankind had not yet travelled into Space and Mt. Everest had not yet been conquered, just to name a few things.
In this other reality he is no longer a scientist but rather a well known author. He also finds that he is married to a beautiful woman who he instantly falls in love with but who his alternate self never cared for. He has some difficulty convincing anyone that he is not actually who they think he is. With the help of a physics professor who believes his story, he finally manages to convince his ‘wife’ that he is not the man she knew before. After a personal tragedy in this alternate world, he finds himself back in his own world and desperately trying to locate the woman he fell in love with in the other world. Little does she know, however, that her life depends on him finding her.
Based on the story Random Quest by John Wyndham.
