The project is called Adrift and is based on a true story of “a woman who sets off on a sailing trip to Tahiti with her fiance. But after a massive storm, the woman finds herself alone at sea with her boat in ruins.”
According to THR, the story, which toggles between the couple’s past courtship and the perilous present, follows her attempts to save herself and the man she loves on a 1,500-mile journey to Hawaii.
Shailene and Miles have starred in four movies together: Divergent, Insurgent, Allegiant and Spectacular Now.
