The first film featuring the stars of The New Generation TV series sensibly revives the Borg, Captain Jean-Luc Picard's implacable enemy, who threaten all of civilisation. When the Borg's assault on Earth in the 24th century fails, they travel back to the 21st century to change history, pursued by Picard and his crew, who must also contend with a Borg force on the USS Enterprise-E.
