We’ve already heard about the scripted series pick-ups on The CW, but today the network has released their full schedule and the official series synopses for all the brand new series. Below you can find details on the drama/thriller series Ringer which will mark Sarah Michelle Gellar’s return to television, Vampire Diaries-companion The Secret Circle, medical drama Hart of Dixie, the Mario Lopez-hosted reality series H8R, another modeling reality show called Re-Modeled and a game show called The Frame.

Details, the first images from the new series, and the full 2011-2012 schedule can all be found after the jump.

With upfronts in full swing, The CW has announced several bits of information regarding its Fall 2011 slate. First up, the good news (for the series’ involved, at least): Nikita and One Tree Hill (which will most likely outlive all of us) have both been renewed for their second and ninth seasons respectively. On the other side of things, InsideTV is also reporting that cheerleading drama Hellcats will not return for its second season.

In addition to its renewals and cancellations, The CW has also announced a number of new shows set to premiere later this year. Most notably of these is the drama/thriller series Ringer which will mark Sarah Michelle Gellar’s return to television. Ringer ends up at The CW after being passed on by its parent network CBS who claimed that the pilot didn’t align with its brand (which, for me at least, is an indication that the show may actually be worth checking out). In addition to Ringer, the network also added Vampire Diaries-companion The Secret Circle, medical drama Hart of Dixie, and the Mario Lopez-hosted reality series H8R (which may take my own personal award for “Worst Idea I’ve Ever Heard”). Hit the jump to check out official synopses for each of these new shows.
