In the first season, Oliver comes back to Starling City and is brought together with his mom, Moira (Susanna Thompson), his sister, Thea (Willa Holland), and his companion, Tommy Merlyn (Colin Donnell).
The series follows very rich person playboy Oliver Queen (Stephen Amell), who professed to have gone through five years wrecked on Lian Yu, a strange island in the North China Sea, before getting back to Starling City (later renamed 'Star City') to battle wrongdoing and debasement as a mystery vigilante whose weapon of decision is a bow and arrow.
