Greenhouse.

The show is about two kids; Ellali and Alfie Reshef, who lose their astronaut mother, in a freak explosion, as she's going up in the shuttle. The two then enroll at the Greenhouse, an elite boarding school for future leaders. Alfie and Ellali are split into two separate teams; being the Eagles and the Ravens. Throughout the series the two teams compete against each other in team-building and leadership challenges throughout the school semester. However eventually most members of the Ravens and key members of the Eagles notice strange goings on around the school and are forced to join forces in order to save the world.
