Hola

Set in the modern day, you, a tired (first assistant) surgeon, have come to see the worst of what humanity has to offer. From long work shifts, the bleak and dull atmosphere, and witnessing grief upfront, you've just about had it with life up until now. What you fail to realize is that fate doesn't seem ready to let you give up so easily though, deciding to spruce up your life by sending you "gifts" that date back to the 18th century. On the opposite side of the coin, three soldiers from different countries find themselves fighting against Hell itself, watching men rise from the dead and tearing through humanity. Each of which struggle to fight against these hordes while also battling something within their hearts. When they think they're about to meet their end, each man finds himself bewildered at the sudden shift in the environment, befuddled by the strange situation they've been placed into. The person staring across at them could say the same. OR 3 soldiers get sent into the future and they all end up becoming your responsibility lol
