Jonathan Merris is a scientist who invents his personal time machine. Brilliant man of science - as much as careless - he decides to be the guinea-pig of his most important experiment. When he starts his first travels, he will find out that he is not the only time traveler, thereafter the surprises will upset his view of the world and his same life. Upsetting revelations will be supplied to him by an unusual encounter with a woman who will show him – with his own eyes – the humankind’s fate. Aware of the importance of his experiences, he writes down them in a manuscript as evidence, hoping that his information – in case of accident – will arrive entirely to us. Adventures, revelations, archaeological enigmas will come to light thanks to this manuscript, surrounded by a singular love story which crosses the time boundaries.
