The 'nothing to lose true story' might involve a character who has faced numerous setbacks in life, perhaps lost their job, their home, or had a difficult relationship end. In this state of having seemingly lost everything, they embark on a journey of self - discovery or take on a challenging task. For example, they might move to a new city where they know no one and try to build a new life from scratch, with only their determination and the idea that they can't be in a worse situation.
Well, without more context, it's hard to give a detailed account of the 'nothing to lose true story'. But generally, it could be about someone at a crossroads in life. Maybe they're dealing with an illness and decide to live life to the fullest despite the odds, or they're in a financial mess and take a leap of faith into an unknown career path. They see that they've already hit rock bottom in some ways, so they're willing to take risks that others might not because they feel there's no downside left.
