Styx(2018)

Rike is forty, a successful doctor whose job demands everything of her. She intends to use her much-needed annual holiday to fulfill her long-cherished dream of sailing alone from Gibraltar to Ascension, a small tropical island in the middle of the Atlantic. Her desire for a carefree holiday seems to be coming to pass but then, after a storm, her beautiful adventure suddenly turns into an unprecedented challenge when she spots a badly damaged, hopelessly overloaded refugee boat nearby.
