Watch Horizon Line (2020) online

Horizon Line, directed by Mikael Marcimain, tells the story of Jackson (Alexander Dreymon) and Sara (Allison Williams), a couple who board a local flight to the Caribbean to attend a wedding on one of the islands. The small plane is flown by Sara's friend, Wyman (Keith David), who asks her to sit as a co-pilot while Jackson sleeps in her main cabin.
During the flight, however, Wyman has a heart attack and suddenly dies, leaving the command to Sara, who, unaware of how to fly a plane, initially risks sending the aircraft into free fall. The couple realize that the autopilot is damaged and they will have to try to drive the small plane themselves. As if that weren't enough, the flight seems to be headed for a storm ... Will the two be able to survive and reach dry land safely?
