Susan Lake bought her 950-square-foot Greenlake Garden apartment entirely with her own cash, the deed in her name alone. One Friday after overtime, she comes home to find a pair of size-7 ivory stiletto heels in the entryway—her husband Frank's first love, Julia, has moved into the master bedroom, wearing Susan's silk nightgown and using her SK-II. Her mother-in-law Miranda arrives, openly treats Julia as the real daughter-in-law, forces Susan to sleep on a floor mat, and secretly plots to trick Susan into adding Frank's name to the deed so they can divorce and split the property. Outwardly docile, Susan quietly contacts her childhood friend Rex Hawk, sells the apartment for an all-cash $1.35 million—$50k above market—and transfers the deed, while secretly repairing the surveillance cameras to record every conspiracy. On the tenth day, Susan returns with Rex and four men, presents the new deed and purchase contract, forces Julia to repay $1,442 for fifteen days of freeloading, and makes Frank sign the divorce papers. Learning the house was never Frank's, Julia leaves coldly; Miranda's tantrums fail; Frank slumps at the gate clutching Rex's card reading "you don't deserve her." Susan hails a cab and heads to the mall for a fresh set of SK-II.
