Based on a book by Lucy Clarke, The Castaways is about a tropical holiday gone wrong.

When two sisters traveling around Fiji have an argument, they split up. Erin decides to stay where she is on their island-hopping trip, while Lori gets on a plane to travel elsewhere. When the plane disappears, Erin thinks she's lost her sister... until her credit card is used in a remote village in Fiji.

In this tense mystery-thriller, we see Lori as she has to survive in the wild, while Erin tries to figure out what happened to her sister. It's like Lost meets Yellowjackets, except you won't have to wait for each episode to come out.

So here's how to watch The Castaways from wherever you are... if it's streaming for you.
