This summer sees the return of the Killjoysfor its fourth season. At the end of last season, we saw our trio split up. But now the team has reunited with the knowledge of their true enemy's name. "The Lady" is described as an immeasurable manifestation of evil without beginning or end. Dutch (Hannah John-Kamen), Johnny (Aaron Ashmore), and D'av (Luke Macfarlane) have something The Lady wants, and she's making her play for it.

Syfy's science fiction action/adventure will make its Season 4 premiere on Friday, July 20 at 10/9c. You can also stream it on Syfy.com or the Syfy Now app, if you have a login from your cable provider. If you don't have cable television, then you can watch Syfy shows through the fuboTV streaming service, where there's a 7-day free trial period for new subscribers.

There are 10 episodes planned for the fourth season, lasting throughout the rest of summer and wrapping up just in time for the fall. Killjoys has already been renewed for a fifth and final season, and those last ten episodes are expected to land on television in 2019. Don't miss the exciting two-season conclusion of this epic series!
