Shortly after the death of her mother, medical student Nancy Adams (Blake Lively) travels to a secluded beach in Mexico, the same beach her mother visited while she was pregnant with Nancy. Carlos (Oscar Jaenada), a friendly local resident, gives her a ride and drops her off at the beach. Nancy joins two other locals, and the three surf for several hours. Taking a break from surfing, Nancy video-chats with her sister Chloe (Sedona Legge). When she talks to her father (Brett Cullen) in an emotional and strained conversation, it is revealed that her mother’s death caused Nancy to consider dropping out of medical school.
