In the future (?), memories are able to be downloaded and backed up. During a procedure a man wakes up in a body that is not his own and proceeds to act in an illogical way. That pretty much sums it up. It didn't really make much sense.
EDIT: To clarify, I understand the plot, and what happens, but there's unanswered questions and some illogical points that don't make sense.
It's very Black Mirror-esque, which is good, but it isn't well written. There's too much that doesn't make sense. I spent a good 10 minutes afterwards trying to put it together but not in a fun, mind-bending way. More of a "huh?" kind of way and then just gave up. Whatever. Life's too short to spend on films that don't make sense.
It's an interesting idea to begin with, and throws in some tantalizing concepts, but then proceeds to not follow through with them. I think that the writer had a good initial concept, but tried too hard to make the plot twist and turn rather than laying out a film plot that connects together.
. Who is Gavin? Why did he pay Emma? What's her daughter got to do with any of it? Why does he goes bonkers? Rather than leaving things for the audience to think about, it instead just doesn't tell a coherent story. I tried googling it in the hopes that someone would explain it (since the plot doesn't really make any sense), but alas I couldn't find anything.
