Supergirl Season 3 synopsis:
Supergirl is an action-adventure drama based on the DC character Kara Zor-El, (Melissa Benoist) Superman’s (Kal-El) cousin who, after 12 years of keeping her powers a secret on Earth, decides to finally embrace her superhuman abilities and be the hero she was always meant to be. Twelve-year-old Kara escaped the doomed planet Krypton with her parents’ help at the same time as the infant Kal-El. Protected and raised on Earth by her foster family, the Danvers, Kara grew up in the shadow of her foster sister, Alex (Chyler Leigh), and learned to conceal the phenomenal powers she shares with her famous cousin in order to keep her identity a secret. Years later, Kara was living in National City and still concealing her powers, when a plane crash threatened Alex’s life and Kara took to the sky to save her. Now, Kara balances her work as a reporter for CatCo Worldwide Media with her work for the Department of Extra-Normal Operations (DEO), a super-secret government organization whose mission is to keep National City – and the Earth – safe from sinister threats. At the DEO, Kara works for J’onn J’onzz (David Harewood), the Martian Manhunter, and alongside her sister, Alex, and best friend, Winn Schott (Jeremy Jordan). Also in Kara’s life are media mogul Cat Grant (Calista Flockhart), James Olsen (Mehcad Brooks), a photo journalist who moonlights as Guardian, a masked vigilante, Lena Luthor (Katie McGrath), and Mon-El of Daxam (Chris Wood), whose planet was ravaged by Krypton’s destruction. As Kara struggles to navigate her relationships and her burgeoning life as a reporter, her heart soars as she takes to the skies as Supergirl to fight crime.

Television, with executive producers Greg Berlanti (“The Flash,” “Arrow”), Andrew Kreisberg (“The Flash,” “Arrow”), Sarah Schechter (“Arrow,” “The Flash”), Robert Rovner (“Private Practice,” “Dallas”) and Jessica Queller (“Gilmore Girls,” “Gossip Girl,” “Felicity”).
The Flash Season 4 synopsis:
Barry Allen (Grant Gustin) lived a normal life as a perpetually tardy C.S.I. in the Central City Police Department. Barry’s life changed forever when the S.T.A.R. Labs Particle Accelerator exploded, creating a dark-matter lightning storm that struck Barry, bestowing him with super-speed and making him the fastest man alive — The Flash. But when Barry used his extraordinary abilities to travel back in time and save his mother’s life, he inadvertently created an alternate timelineknown as Flashpoint; a phenomenon that gave birth to the villainous speed god known as Savitar, and changed the lives of Caitlin Snow (Danielle Panabaker) and Wally West (Keiyan Lonsdale) forever. With the help of his adoptive father, Joe West (Jesse L. Martin), his lifelong best friend and love interest Iris West (Candice Patton), and his friends at S.T.A.R. Labs — Cisco Ramon (Carlos Valdes), C.S.I Julian Albert (Tom Felton), and an Earth-19 novelist named H.R. Wells (Tom Cavanaugh) — Barry continues to protect the people of Central City from the meta-humans that threaten it.

Legends of Tomorrow Season 3 synopsis:
After the defeat of Eobard Thawne and his equally nefarious Legion of Doom, the Legends face a new threat created by their actions at the end of last season. In revisiting a moment in time that they had already participated in, they have essentially fractured the timeline and created anachronisms – a scattering of people, animals, and objects all across time! Our team must find a way to return all the anachronisms to their original timelines before the time stream falls apart. But before our Legends can jump back into action, Rip Hunter (Arthur Darvill) and his newly established Time Bureau call their methods into question. With the Time Bureau effectively the new sheriffs in town, the Legends disband – until Mick Rory (Dominic Purcell) discovers one of them in the middle of his well-deserved vacation in Aruba. Seeing this as an opportunity to continue their time travelling heroics, Sara (Caity Lotz) wastes no time in getting the Legends back together. We reunite with billionaire inventor Ray Palmer (Brandon Routh), the unconventional historian-turned-superhero Nick Heywood (Nick Zano), and Professor Martin Stein (Victor Garber) and Jefferson “Jax” Jackson (Franz Drameh), who together form the meta-human Firestorm. Once reunited, the Legends will challenge the Time Bureau’s authority over the timeline and insist that however messy their methods may be, some problems are beyond the Bureau’s capabilities. Some problems can only be fixed by Legends. Based on the characters from DC, DC’S LEGENDS OF TOMORROW is from Bonanza Productions Inc. in association with Berlanti Productions and Warner Bros. Television, with executive producers Greg Berlanti (“Arrow,” “The Flash,” “Supergirl”), Marc Guggenheim (“Arrow,” “Trollhunters,” “Percy Jackson: Sea of Monsters”), Andrew Kreisberg (“Arrow,” “The Flash,” “Eli Stone,” “Warehouse 13”), Phil Klemmer (“The Tomorrow People,” “Chuck”) and Sarah Schechter (“Arrow,” “The Flash”).
Arrow Season 6 synopsis:
After a violent shipwreck, billionaire playboy Oliver Queen (Stephen Amell) was missing and presumed dead for five years before being discovered alive on a remote island in the North China Sea. He returned home to Star City, bent on righting the wrongs done by his family and fighting injustice. As the Green Arrow, he protects his city with the help of former soldier John Diggle (David Ramsey), computer-science expert Felicity Smoak (Emily Bett Rickards), his vigilante-trained sister Thea Queen (Willa Holland), Deputy Mayor Quentin Lance (Paul Blackthorne), brilliant inventor Curtis Holt (Echo Kellum), and his new recruits, street-savvy Rene Ramirez (Rick Gonzalez) and meta-human Dinah Drake (Juliana Harkavy). Oliver has finally solidified and strengthened his crime-fighting team only to have it threatened when unexpected enemies from his past return to Star City, forcing Oliver to rethink his relationship with each member of his “family”.
