Netflix released a trailer for Nyad, the upcoming biopic of swimming legend Diana Nyad, based on her 2015 memoir, Find a Way.

Nyad’s book chronicles her career as a swimmer known for marathon water journeys. In 1975, she swam around the island of Manhattan—a 28-mile endeavor that she completed in 8 hours. She became a global star in 2013 after swimming from Cuba to Florida at the age of 64; the 110-mile trip took 53 hours.

A critic for Kirkus called the memoir “inspiring reading for anyone who has ever dared to dream the impossible.”

Nyad stars Annette Bening in the title role, and Jodie Foster as Bonnie Stoll, her friend and coach. The film is written by Julia Cox and directed by Elizabeth Chai Vasarhelyi and Jimmy Chin.

The trailer opens with Bening reading aloud from Mary Oliver’s poem “The Summer Day.” After a shot of archival footage from an old interview with Nyad, it cuts to Foster trying to dissuade Bening from making the Cuba-to-Florida swim, saying, “Absolutely not. No. That’s insane. Diana, you tried that when you were 28, and you did not make it when you were 28. You’re 60.”

“I don’t believe in imposed limitations,” Bening replies. “The only one who gets to decide if I’m through is me.”

It closes with Foster saying fondly to Bening, “There’s no one more Nyad than you.” Bening smiles in response.

Nyad opens in select theaters in October and begins streaming on Netflix on Nov. 3.
