Ace Lightning is a British and Canadian children's television series co-produced by the BBC and Alliance Atlantis, which originally broadcast in the United Kingdom but was also aired in other countries including the United States, Australia, New Zealand and South Africa.
The programme featured live actors interacting with computer animated characters from a fictional video game. The series is significant in that until its creation, live action and CGI had not been attempted to such a huge and constant degree within a weekly television serial.
The series follows the life of British teenager Mark Hollander who moved to the American town Conestoga Hills with his parents. One stormy night, Mark plays his favourite video game, the fictional Ace Lightning and the Carnival of Doom - a superhero-based adventure game where hero Ace Lightning traverses the Carnival of Doom to find the pieces of the magical Amulet of Zoar, whilst battling his nemesis Lord Fear.
Mark stumbles across a mysterious seventh level which is not meant to exist. A lightning bolt strikes the antenna on his roof, and through an electrical surge, the characters of the game come to life. Ace hires Mark as his sidekick to fulfil the game's objectives in the real world. Mark's life is turned upside-down, and his duty as a Lightning Knight effects his school grades and social life, often forcing him to make excuses to his family and friends. Meanwhile, Lord Fear's group of villains occupy the town's rundown Kent Bros. Carnival.
