High Lane (2009) on Netflix

Plot summary

Chloé, a nurse still carrying guilt over a young patient's death, joins her boyfriend Loïc, her friend Guillaume, and the couple Fred and Karine on a climbing trip to Croatia. Loïc is unpopular with the others and inexperienced on rock, and his fear frequently leaves him stuck until Chloé urges him on. At the trailhead, rocks block the start, but Fred, the experienced climber of the group, talks everyone into crossing the closed route anyway. The trail turns out to be more dangerous than they assumed: a rope bridge collapses just after they cross it, nearly taking Karine down with it. With the bridge gone, the friends cannot turn back, and Fred, who persuaded them onto the closed trail, says they must reach the end as fast as they can.
