Ben, a curious boy, hates having to stay with his old Granny every Friday because his parents go to see a dancing show named "Strictly Stars Dancing" (a parody of Strictly Come Dancing). He finds it boring and repetitive as his Granny always feeds him cabbage-related dishes, most commonly cabbage soup and cabbage chocolate, and they are constantly playing Scrabble, plus her television hasn't been working since the 1990s. Ben loves plumbing and is a long-term subscriber to the magazine Plumbing Weekly, which he buys every week from Raj's news-agency. Ben's parents disapprove of him being a plumber, as their ambition for their only child was to be a professional ballet dancer like the one they used to watch every Friday.

One day, Ben calls his parents at Granny's house and asks them to take him home. Mum and Dad ignore Ben and disapprove of the proposal. Granny somehow overhears the conversation due to the indistinct sound made by Ben while he was talking. The next morning, his Granny seems somewhat upset and disappointed thinking that her grandson doesn't love her.

That same morning, Ben is served boiled eggs by Granny, which Ben doesn't like and he flicks the runny egg gloop onto the window. But, as he was hungry, he starts searching for something to eat; with some pocket left luck, he finds a box of chocolate biscuits. To his surprise, the tin feels much heavier than usual. Ben unscrews the lid and finds many diamonds, rings, bracelets, necklaces and earrings clustered together in the tin. Ben hears Granny approaching and quickly puts the tin back and sits back down at the table completely shocked! He goes home and now can't wait to see his grandma again to find out about these jewels. But when his dad rings Granny up, she says she's too busy that evening to have Ben sleep over.
