Highway Thru Hell - Season 4 is a top class production made in 2015. If a tv show can manage me to stay hooked on the whole tv show online, that's really impressive. If a tv show can keep me focused for the full tv show time, that's really great. Anyway, Documentary may boast of one of the biggest numbers of good tv shows. Whoever has not seen let it rush in front of the TV, because this tv show just has to be seen. Forget the torrents, watch it online here.
