A trailer has gone online for 47 Meters Down, the long gestating shark thriller from director Johannes Roberts (The Other Side of the Door) and starring pop-singer-turned-actress Mandy Moore (pictured above) and Claire Holt (“Aquarius”) as hot cage-diving sisters trapped undersea with great whites.

47 Meters Down finds Moore and Holt vacationing in Mexico off the coast of Huatulco on a cage-diving expedition to observe great white sharks. When cables snap, the cage sinks to the bottom of the ocean and the sisters have less than an hour of oxygen to get back to the surface in shark infested waters.

Moore, who’s starred in a string of romantic comedies and Disney fare, makes her horror debut with the film. Holt jumped into horror in 2009’s Messengers 2: The Scarecrow. After a stint on teen soap “Pretty Little Liars,” she starred on NBC’s Charles Manson drama “Aquarius” and The CW’s “Vampire Diaries” and “The Originals.”

In theaters June 23!
