L'Isola dei Famosi - Season 15

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.

Eight years ago, Citadel, an independent global spy agency, was destroyed by a new syndicate, Manticore. With their memories wiped, elite agents Mason Kane and Nadia Sinh barely escaped with their lives. Eight years later, Mason's former colleague, Bernard Orlick, asks for his help to prevent Manticore from establishing a new world order.

In any given year, more than 600,000 people are reported missing in the U.S. More than half that number are people of color that the country seems to forget about. Public relations specialist Gabi Mosely - who was once herself one of those forgotten ones - and her crisis management team now make sure there is always someone looking out for the forgotten missing people. But unbeknownst to anyone, this everyday hero is hiding a chilling secret of her own.

Earth is visited by an alien species that threatens humanity's existence. Events unfold in real time through the eyes of five ordinary people across the globe as they struggle to make sense of the chaos unraveling around them.

In this workplace comedy, a group of dedicated, passionate teachers — and a slightly tone-deaf principal — are brought together in a Philadelphia public school where, despite the odds stacked against them, they are determined to help their students succeed in life. Though these incredible public servants may be outnumbered and underfunded, they love what they do — even if they don't love the school district's less-than-stellar attitude toward educating children.
