The film follows several intertwining narratives as the security cameras watch over the characters in several different areas: a gas station, a high school, a mall and an office building.
The storylines progress over the course of a week and many of the characters end up interacting with each other in the course of their lives.
A day later, Lydia eventually hears from Naomi that Tony has had sex with her as well.
When confronted, Tony tries to twist the conversation around, citing Lydia's husband and three kids, and eventually reconciles with her through more sex.
Other security camera footage shows Tony having sex with multiple employees.
A few days later, Tony attempts to hit on Courtney, who flatly refuses his advances and notifies him of a previous sexual harassment lawsuit that she had to settle with her previous employer.
Courtney eventually tells Lydia, who pretends that only idiots sleep with Tony.
Office worker Marty down on his luck: the ATM eats his card, he is awkward with social interaction and he ends up being the target of several pranks at his firm, ranging from spiked soft drinks and drawers filled with sour cream, to the wheels from his car removed.
Over the course of the film, Marty becomes increasingly upset by the wide range of pranks pulled on him and eventually explodes his frustration onto the co-worker who pranks him.
Ben and his wife Louise install cameras into their house to look after their baby while they are at work.
Their daughter Megan ends up being the target of a pedophile over the course of two days, when she and Louise shop for clothes, housewares and toys.
