The invasion occurs under mysterious circumstances and Barry (Grant Gustin), Iris (Candice Patton) and the rest of Team Flash are pushed to their limits in a desperate battle to save the world.

But with time running out and the fate of humanity at stake, Flash and his companions will also need to enlist the help of some old friends — like Ray Palmer (Brandon Routh), Batwoman (Javicia Leslie), Black Lightning (Cress Williams), Green Arrow (Katherine Grace McNamara) and others.

Here's everything to know about how to watch the The Flash season 8 online. Plus, check out a promo:

How to watch The Flash season 8 anywhere on Earth

Just because The CW isn't available everywhere doesn't mean you need to miss The Flash season 8. Watching along with the rest of the internet can be pretty easy. With the right VPN (virtual private network), you can stream the show from wherever you go.

We've evaluated many options, and the best VPN is ExpressVPN. It meets the VPN needs of the vast majority of users, offering outstanding compatibility with most devices and impressive connection speeds. It's also affordable at $12.95 per month. (Signing up for longer periods of six months or a year reduces the cost even more.)

ExpressVPN

Our favorite VPN service, ExpressVPN, really shines thanks to its safety, speed and simplicity-to-use. It's also compatible with loads of devices - from iOS and Android to Roku, Apple TV and PlayStations. You'll even get an extra 3 months free if you sign up for a year, or there's a 30-day money-back guarantee if you just want to give it a try.

Using a VPN is incredibly simple.

1. Install the VPN of your choice. As we've said, ExpressVPN is our favorite.

2. Choose the location you wish to connect to in the VPN app. For instance if you're in the U.S. and want to view a U.K. service, you'd select U.K. from the list.

3. Sit back and enjoy the action. Head to your website or streaming service of choice and tune in.
