This post is going to contain FULL SPOILERS for the movie 6:45. Do not click to view these spoilers unless (A) you want to know them and (B) you want to have your day ruined by the wasted potential that is this movie.
As I said earlier, the elevator pitch for this movie is that it's about a couple on vacation, but they keep getting murdered and then waking at 6:45 AM on the same day. I might miss a couple small things but to the best of my recollection this is what occurs in the movie:
The movie begins with a sex scene. Why? I'm not sure. It's just footage of people having sex. There are several sex scenes in this movie and it's not really clear why.
Hard cut to the same couple on the top floor of a ferry as they travel to their vacation spot.
Now they have reached their destination called Bog Grove and they walk to their bed and breakfast to check in. They remark that there doesn't really seem to be anyone else on the island. The male characters name is Bobby and the female is called Juliet or Jules. It is mentioned the Bobby visited this island when he was a small child and doesn't really remember or recognize it, but they thought it would be a good place to get away for a few days.
They check in with the owner of the BnB, Gene. He's a kind of unkept sort of person. Kind of like Timothy Spall's Peter Pettigrew from the Harry Potter movies sort of vibes. They go up to their room. It is that evening now and they are in bed. Gene knocks on their door to check on them, it seems he has a habit of being nosey. They say they are fine and then there is another sex scene. Possibly just a repeat of the same sex from before, it wasn't different enough for me to be sure it wasn't just the same footage from the top of the movie. They go to bed and the loop begins.
The beginning of day 1:
The alarm goes off a 6:45. Neither of them remember setting an alarm. Gene knocks on the door to check on them and says breakfast will be ready soon.
Bobby gets up to use the restroom. Jules says she is going to call her mother to let her know she got to the island and is still alive. Bobby tells Juliet to tell her mother that he says "hi".
While in the restroom Bobby looks at the bar of soup and notices it has a clump of hair stuck to it. He is visibly grossed out by this so I assume this wasn't just his own hair from the night before. [Did neither of them use the restroom the night they checked in?].
After leaving the restroom bobby grabs a pack of cigarettes, noting that there are only 2 left in the pack. He wonders aloud if he would be allowed to smoke in the room and Jules says she doesn't think so.
Before they leave the hotel room Bobby notices an envelope addressed "To Bobby". He asks what it was and Jules says it's something she wrote when they were fighting before their vacation. The implication seemed to be that things weren't going well between the two of them, but they are trying to make it work.
They go down to breakfast. When Gene arrives with the food Bobby mentions that the restroom was dirty. Gene apologies and says he'll have their maid take care of it. Jules asks Gene why the island seems deserted. Gene looks like he is going to say something but then instead says it's better not to talk about some things and the past is in the past.
After breakfast they walk around the island. They stop at a thrift shop. Jules examines a pair of yellow high heels. Jules sees a sign that has "JULES" written on it. Jules poses with several pairs of sunglasses.
