According to the show’s official logline: Green Lantern reinvents the classic DC property through a story spanning decades and galaxies, beginning on Earth in 1941 with the very first Green Lantern, secretly gay FBI agent Alan Scott, and 1984, with cocky alpha male Guy Gardner and half-alien Bree Jarta.
