Horizon

The lives of five people are forever changed when a mysterious alien ship appears on the skyline over Bristol. Its intentions unclear, the disparate group attempt to flee the city and reach loved ones, but their efforts are impeded by a city in panic, looters, and the threat of military attack. As they battle to stick together, loyalties and relationships are tested, and an even larger question remains: who are these mysterious visitors and why are they here?
