Mrs. Sidhu's first day catering for Sharpetone, a high-end health club, takes a turn of the unexpected when two bodies are found dead in the spa. Despite her knack for solving mysteries, Mrs. Sidhu tries her best to stay out of it. But when her niece, Rani, becomes the police's number one suspect, Mrs. Sidhu takes it upon herself to start her own investigation and prove them wrong. This brings her into conflict with the Chief Detective on the case, Inspector Burton, who has no patience for her theories. Her investigation leads to uncovering business secrets, feuds between colleagues, and well-hidden love affairs.

Mrs. Sidhu's knack for crime solving is put to the test again when she and Tez cater for the convention of hit fantasy TV show, Swordmaster, written and created by the Melville family. But when life imitates art and one of the lead cast is found dead in the woods, killed the same way another character was murdered in the show's previous seasons, things go from fantasy to reality very quickly. When Mrs. Sidhu is asked to stay on and cook for the Melville's while they grieve, she can't help but find suspicious clues. Much to his dismay, Mrs. Sidhu is reunited with Chief Inspector Burton. His theories of who the killer is don't match up with hers, and his reluctance to hear her out leaves her no choice but to start her own investigation and prove him wrong.
