Three people from different centuries are recruited by a mysterious organization whose purpose is to make sure that the history of Spain proceeds as it should. A 16th century soldier, a 19th century university student, and a 21st century paramedic, each bring to the table indispensable talents and a shared courage that bind them into a formidable team.
I am not going to say this shows concept is anything original, it is not, there is a plethora of shows that revolve around the concept of time travel. Slider & Quantum Leap to name but two.
What makes this show stand out from the crowd are a number of things
1: It is not always 'family friendly' it uses expletives, there is nudity it touches on subjects that other shows would avoid in favour of popularity (murder, child abduction, etc, etc, etc)
2: The actors, Nacho Fresneda, Juan Gea, Cayetana Guillén Cuervo & aime Blanch all stand out adding humour & gravitas to the show.
3: History, every show these days feeds us American & British history and I imagine like most I take what I am told for granted, because for the most part I know a little of the history being told. But being Spanish, this show had me Googling every episode. Whoever wrote this, either had a passion for Spanish history, or spent an amazing amount of time researching, the good, bad & funny parts of Spanish history.
4: the photography and sets, I suspect this show doesn't have the kind of budget that Agents of SHEILD or other such shows can boast, this show looks just as polished as any of them.
It will be interesting to see what Netflix (who have apparently brought the rights to this show) do for season 4, personally I hope they allow the actors & writers to carry on as they have.
