She is saving up $25,000 in gold, enough to live off-grid and save herself at the end of the world. How will she make the money? An investment app called Matador.

Then she gets a pointer from an online forum: an obscure Australian wine company is poised to surge. She sinks most of her savings into it.

Now, she waits.

Out of nowhere, Freya, her best friend from high school, reaches out. She’s a single mum in the middle of a nightmare divorce. In other words, she needs money, fast.

So . . . Ellie tells her about the vineyard. But Freya does more than invest.

She starts sharing financial tips with other women online. The stock takes off. And things start going wrong. Investors report strange ailments, horrific accidents. Rumours spread online. Is the stock cursed? And if this is the cost of making money while you sleep, do you stick it out or run for the hills?
