Struggling writer Bradley Cooper is persuaded to take a revolutionary new pill that enables the brain to power at 100% capacity.

The results are astounding, making him super-successful – able to master foreign languages in a day, charm the most beautiful women and make gazillions on the stock market.

However, it’s not long before Wall Street mogul Robert De Niro wants in on the action, thugs are on his trail and, even worse, the pills begin to show their extremely nasty side effects.

This is a fast-paced, hugely enjoyable thriller. Director Neil Burger’s stylish images do a dazzling job of conveying the supercharged mental state of Cooper, who has just the right balance of cockiness and charm to carry off this outlandish thriller.
