The 2023 film Missing has a lot of plot holes and unfinished storylines. Missing is a spiritual successor to the 2018 film Searching, as it follows a similar plot and even features the previous film's storyline in a fake Netflix show called Unfiction. However, while Searching focuses on David Kim using technology to find his missing daughter, Margot, Missing follows June Allen as she searches for her mother, Grace. Missing's plot requires a lot of focus and attention to follow, and still, there may be many moments that are confusing to viewers.
