The Stranger Things season 4 teaser has arrived. Fans of the hit Netflix series were given a pretty sweet Valentine's Day gift with the return of David Harbour's Chief Hopper. That's right, Hopper is alive and somewhat well in the premiere footage from the highly anticipated season 4. We all thought that he was blown to smithereens during the final episode of season 3, though fans knew deep down there had to be a way that he survived the explosion.

The Duffer Brothers announced today that production on Stranger Things season 4 is now underway. They were pretty excited to let fans know that Hopper is alive, but they did note that there will be some difficulties for the character. They said, "it's not all good news for our 'American'; he is imprisoned far from home in the snowy wasteland of Kamchatka, where he will face dangers both human... and other." What does this mean for the citizens of Hawkins? "Meanwhile, back in the states, a new horror is beginning to surface, something long buried, something that connects everything," notes the Duffers.

According to the Duffer Brothers "[Stranger Things] season 4 is shaping up to be the biggest and most frightening season yet, and we cannot wait for everyone to see more." That's saying a lot since the last three seasons have had their fair share of scares. They went on to say, "In the meantime - pray for the American." We have no idea how Hopper, or "the American," is back or how he was magically transported to Russia, but we'll soon find out.

In the Stranger Things season 4 footage, we are shown some men working on a railroad in the snow. The location is the Russian Far East and the camera starts to go down the tracks a bit until we see one man who needs to take a breather. The man removes his beanie to reveal the shaved head of Chief Hopper. He appears to be in some kind of labor camp and the conditions look less than inviting. If anyone can figure out a way out of this mess, it's going to be Hopper, though he may need a little help from his friends when all is said and done.

There is currently no official release date set for Stranger Things season 4. With Netflix already starting to tease the first footage and Hopper's survival, fans might end up getting to see the new season sooner, rather than later. So far, it does not look like the series will return this summer. Instead, it's likely that we will see a return in either the fall or perhaps the end of the year. At the most, the streaming giant may make everybody wait until early next year. You can check out the first footage from Stranger Things season 4 above, thanks to the Stranger Things YouTube channel.
