Goofs

Samantha's regular locker has no lock as do the others.

In the sex scene, they began with Bryce facing the camera. They then reversed positions and Samantha's top was taken off. They then reversed again, so Bryce was facing the camera for the majority of the scene. As such, both faces would have been visible on the security footage, yet the only face visible later was Samantha.

When the power fails, it is pitch black in Samantha's room, yet when she exits the room there is some light there as well as in the hallway beyond what her phone is putting out. Likewise, a few minutes later when Samantha wakes up at 3:13 AM and turns on a lamp, it is clearly daylight outside her window.

The drug screen result form has several errors. The city listed is Los Angeles and the ZIP code 90555 aligns with a southern California location, but the state is Ohio. The reason for the test is shown as both for cause and random. It would be one or the other but could not be both. The line for cocaine is not completed, while every other line was completed. Despite Bryce saying it was the original copy (an oxymoron- it is either the original OR a copy), the form was invalid as it was not signed by the donor, who was listed as Gina. The last point would be an indicator it had been faked.

Recently deleted text messages can be easily recovered from both iPhones and Androids. There's an app for that.

In the hallway by the lockers when Lucas first talks to Samantha, the sign behind him has swim misspelled as "swimm".

After Samantha comes home the first time, as she walks past her mom and then turns to go upstairs a wire for her microphone is visible on her right hip going up into her shirt.

Bryce says he is not a teacher or even a school employee. As such, he would not have access to the school's video system to obtain the footage from the pool.

In the pool sex scene, Samantha's swimsuit top is removed and is seen on the bottom of the pool, but her bottom was never removed and is seen in place during the scenes.
