Yes, it's Triangle. I really enjoyed watching it. One of my friends in university told us he wanted to show us an amazing movie, but didn't tell us anything else about it, which I think made it much better than if I'd known what to expect.
Some may think the film is a bit overrated but it's easily one of my all-time favourite science fiction flicks. It holds up beautifully 20 years later, and I love that this film's stunts were mostly practical where its sequels went much harder on the CGI. The fantastic Trinity wall-run at the very beginning of the movie never fails to get me hyped for what's to come, and the film never disappoints.
