From the writers of The Avengers and X-Men: The Last Stand comes an action-packed series about five ordinary people brought together to form one extraordinary team of Alphas — people with the unique power to stretch the capabilities of the human mind giving them superhuman physical and mental abilities. Led by Dr. Lee Rosen (Emmy Award-winner and Academy Award-nominee David Strathairn), an expert in Alpha phenomena, the team investigates cases that point to others with Alpha abilities. As they work against the clock to solve this new brand of crime, they must prevent their own personality differences and disparate backgrounds from interfering with their ultimate mission to catch the enemy. This season, all hell breaks loose after Dr. Rosen’s revelation of the existence of Alphas to the world and the Red Flag plot thickens. The dismantled team of Alphas needs to be brought back together to save the lives of two of their own, when Gary and Bill are taken hostage.
