After receiving a callous text from her husband Carl announcing he’d married his coworker Monica in Vegas after an eight-month affair, Diane calmly replies “Cool” before spending the pre-dawn hours canceling his cards, changing every password, and having the locks replaced on their house. By sunrise, Carl is locked out of every account and door he once had access to, and Diane finally sleeps peacefully for the first time in hours.

That peace is short-lived when heavy pounding on the door wakes her at 8 a.m. Looking through the peephole, she finds two tired police officers standing outside, suggesting the fallout from her decisive overnight actions has already escalated into something requiring official attention.
