Changed this request a bit at the end.
"Teresa is a single, prudish middle aged woman frustrated with her boring life, who owns a barely profitable antique shop. Due to her financial difficulties, she is forced to rent part of her home to Julia, a college student. Teresa's bitterness towards the young woman increases after discovering that Julia works at a local strip club, and earns way more than her.
One day, while doing the inventory of her shop, Teresa finds a box labelled "Costume Gun". Inside the box, there is a strange metallic device and a very brief user's manual. At first as a joke, Teresa begins to wonder if she could use the artifact to escape her own dull existence and usurp Julia's."
