The Source Of River - Season 1

Emmy Award and Grammy Award winner Jimmy Fallon brought NBC's "The Tonight Show" back to its New York origins when he launched The Tonight Show Starring Jimmy Fallon from Rockefeller Center. Fallon puts his own stamp on the storied NBC late-night franchise with his unique comedic wit, on-point pop culture awareness, welcoming style and impeccable taste in music with the award-winning house band, The Roots.

Countdown begins with a suspicious murder in broad daylight, leading Los Angeles Police Department officer Mark Meachum to be recruited to a secret task force of undercover agents from all branches of law enforcement that will investigate the death. But as the truth of a more sinister plot comes into focus, the team must overcome their conflicting personal agendas to unite and save a city of millions.

London, 1946 is the dynamic, dangerous and chaotic setting for this stylish new detective drama, with the eccentric Gabriel Book at the very heart of the story: a self-appointed consultant detective to the local police. The thousands of books that line the shelves of his shop provide him with all the knowledge he needs.

Book has gathered around him a host of lovable, damaged misfits whom he informally protects, cajoles, and mentors. His wife Trottie runs the wallpaper shop next door. She's a charismatic adventuress whom Book loves deeply but not physically, for they are in a 'lavender' marriage to help conceal Book's sexual orientation in a time when it was illegal to be gay.

Bookish marries post-war nostalgia with the reckless and life-affirming atmosphere of the times, creating a fast-paced and stylish detective drama.

Seth Meyers, who is Saturday Night Live's longest serving anchor on the show's wildly popular "Weekend Update," takes over as host of NBC's Late Night — home to A-list celebrity guests, memorable comedy and the best in musical talent.

As the Emmy Award-winning head writer for "SNL," Meyers has established a reputation for sharp wit and perfectly timed comedy, and has gained fame for his spot-on jokes and satire. Meyers takes his departure from "SNL" to his new post at "Late Night," as Jimmy Fallon moves to The Tonight Show.

Jimmy Kimmel Live features a diverse lineup of guests that include celebrities, athletes, musical acts, comedians and human-interest subjects, along with comedy bits and a house band.
