We Were Liars: Season 1 (June 18)

Kind of like a combination between I Know What You Did Last Summer and The Summer I Turned Pretty, this juicy mystery-drama sees the sunny season as a total bummer: sunbathing, way too much time off, and companions who aren’t what they seem. It’s based on the best-selling novel by E. Lockhart, and follows the heir to a fabulous New England estate—and her pack of best friends, who paradoxically call themselves ‘the Liars’. Could one of them (gasp!) be lying about the dark events that happened during their fifteenth season together?

Neatly packing away a monster twist for its last few episodes, this secretive series should also just offer a well-needed bit of aspirational glam, considering its Kennedy-esque setting and cashed-up protagonists. You can even watch it in the dead of winter, wishing you were at the end of a sunny dock on a lake with some very…very trusted pals.

Countdown: Season 1 (June 25)

The very handsome Jensen Ackles gets his own absorbing cop thriller, starring as an LAPD detective swooped up into a secret undercover task force. They’re on the trail of a killer, of course, who just claimed the life of the Department of Homeland Security in a shocking broad-daylight slaying. With Eric Dane and Jessica Camacho in the supporting cast, our hunky investigator will certainly uncover deeper and more sinister roots underlying the assassination than anyone could’ve expected. The race against time will be riveting: let the countdown begin.

Deep Cover (June 12)

If you’ve ever hung out with improv fans, you’ll know they are a) lovably annoying and b) willing to do anything, due to that whole ‘yes and’ mantra they live by. Bryce Dallas Howard, Orlando Bloom and Nick Mohammed play just such a part, in this rollicking action-comedy with a twist. Yanked from their hobby into a dangerous London gangland plot by undercover cop Sean Bean, the trio will have to improv their way through situations that are no joke, for once—and I’m hoping that means a lot of shitty UK accent work.
