The fourth season of Stranger Things will reveal some dark secrets about fan-favourite Jim Hopper. The Netflix sci-fi series is due to return for its fourth season and David Harbour is due to reprise his role as the grouchy police chief.
Hopper was seemingly killed-off in the season 3 finale, but a trailer for the fourth run has confirmed that he is alive and is the mysterious 'American' being held captive by the Soviet Union in.
The clip shows a head-shaven Hopper as a prisoner on a snowy Russian landscape being forced into carrying out labour for the army.
Now Habour has teased when speaking to Deadline that fans can expect to learn much more about Chief Hopper in the fourth run and it will be much darker than what we have seen
