Trivial thieves hatch a plot to heist big business’s grand scam: the cure for cancer.

Hello,
me too I don't understand what 'grand scam' means here. Try to tell it straight: what do the thieves must steal?

What Richiev said.

And how can one "heist" a cure for cancer? ?What does that mean? It's unclear whether "scam" means Big Pharma is making big bucks off a high priced bogus cure. ?Or whether Big Pharma is making big bucks off a real cure by charging too much. ? Please clarify.
