We see this man and a woman approach some kind of destiny in the beginning, he explains how she may be going thru hell in the place shes about to stay, but shes calm and she accepts it,She is Alicia (Lucia Mendez) and as she gets institutionalized in a psychiatric ward for the insane, A.K.A."Loony Bin" she starts making friends on the inside like a nurse called Montse and a guy who's deeply afraid of water named Ignacio "Nacho" Rojas and he's masterfully played by Alejandro Camacho that to me is THE BEST Mexican actor of the last years, hope you're reading Alex in a big fan.They are the 3 main characters but we also get a very young Gonzalo Vega as a Doctor who is falling in love with Alicia, we have the classic nurse Ratched here that hates everyone and screams to the insane and stuff like that, we have a vicious hunchback who is always horny and on the loose in this god forgiving place, as its title says "The Twisted lines of God" cause thats the way Nacho refers to Alice as of the content of that place.This great piece of Mexican old film industry is a piece very hard to find,now a days part of my vast collection it truly stands out as one of the good old Mexican movies that time does nothing to it.I like the way they play with the idea that shes insane...and then shes Sane..and then you're wondering if shes o.k or not...you're never sure and they always have some trick down their sleeve so you get to see the whole thing and get the twists of story as good as they get.I liked it and my sisters always made me see this movie when i was a kid..I don't know why..they used to love it,I tried to get it all over these years and now i can fully say i have got it after all this time. If you ever find it see it and you'll like it...Oldtime Mexican treasure.Ill give it a 9 out of 10 cause of its plot twists.
