Horizon(2015)

In 2015, everything changes.

Horizon is a British science fiction series that follows five strangers whose lives collide when an alien spacecraft materializes over Bristol. With the city descending into chaos—panic, looting, and military intervention—the group attempts to escape and reunite with family, but their survival depends on staying together. As tensions mount and trust fractures under pressure, they're forced to confront a deeper mystery: what do these visitors want, and what are they willing to do to get it? The series explores how ordinary people respond to extraordinary threat, testing bonds of loyalty and revealing who people truly are when everything falls apart.
