Plot Summary:
The series follows five people, known as "Alphas", led by noted neurologist and psychologist Dr. Lee Rosen as they investigate criminal cases involving other suspected Alphas. Rosen and his team of Alphas operate under the auspices of the Defense Criminal Investigative Service, the criminal investigative arm of the U.S. Department of Defense. While investigating these crimes, it does not take the team too long to discover that a group known as "Red Flag", which was thought defeated and eliminated long ago, is using other Alphas to commit crimes. With the inclusion of Dr. Calder in the episode "Never Let Me Go", it was established that Alphas takes place in a shared universe with Eureka and Warehouse 13. (from Wiki)
