Erin Plant is a private investigator who specializes in tracking down stolen cryptocurrencies. In March 2022, she received the biggest assignment of her career. It turns out that hackers broke into his online game called Axie Infinity and stole more than $600 million worth of his digital money.
It was the biggest cryptocurrency heist in history. Now it was Erin’s job to find the money and get it back.
Erin’s investigation brings her face-to-face with the world’s most formidable digital money launderers, whose actions soon raise alarms at the highest levels of government and even threaten the planet’s entire nuclear security.
