A sunken Mayan city provides an effectively creepy setting for this fright-packed in-name-only sequel to the 2017 horror hit. Deep within a maze of dark and deadly undersea passages, a quartet of teenage girls (Sophie Nlisse, Corinne Foxx, Brianne Tju, Sistine Rose Stallone) encounters ravenous sharks that will seemingly stop at nothing to turn the young ladies into their next meal. With John Corbett and Nia Long. 90 min. Widescreen; Soundtracks: English DTS HD 5.1 Master Audio, DVS; Subtitles: English (SDH), Spanish; featurette; audio commentary. Two-disc set.
