This is a tightly written and expertly executed suspense from writer/director Seaton Lin. I was thoroughly engaged for its entirety. The female lead, while maybe not likable to some, was a refreshing change for me, because she just is who she is and is doing her job without apology. It had strong performances all around and lovely cinematography. The edits were invisible, not used stylistically, but strongly in service to the story. And the story reins supreme here, it had me at the edge of my seat. Excellent feature debut!
