After years of enduring her domineering mother-in-law Odette and her husband Mathieu’s passive refusal to defend her, Juliette finally reaches her breaking point the night Odette cuts the power to the air conditioner and calls her lazy in front of everyone. Packing her suitcase, Juliette discovers a sealed envelope her late father left her, one containing a property deed and an attorney’s contact information she never knew existed.

When she calls the attorney, Maître Faucher reveals that Mathieu has known about her father’s hidden legacy since their wedding day, and instructs her to look behind the electrical panel, the very place Odette stands triumphantly beside, for something her father concealed specifically so her in-laws would never find it.
