One of the best sci-fi TV shows I’ve seen in awhile! It revolves around multiverse concept, and it’s about how the choices that we make in life leads to different paths.
This TV show is centred around a scientist called Jason Dessen, who made a life choice that he later regretted in life - not being with the woman he love. He then built a box to travel to an alternate version of his life, which he’s happily married to the woman he love. He kidnapped that version of himself so he can be with that woman and yet be successful.
