Timeline is a 2003 science fiction adventure film directed by Richard Donner and based on the novel of the same name by Michael Crichton. The film stars Paul Walker, Frances O'Connor, Gerard Butler, Billy Connolly, and David Thewlis.
The film begins in the present day, where a group of archaeology students and their professor, Edward Johnston (played by Billy Connolly), discover a medieval artifact at an excavation site in France. However, while attempting to retrieve another artifact, Johnston is accidentally transported to 14th century France through a wormhole created by the artifact.
The rest of the group, led by Johnston's son, Chris (played by Paul Walker), and his love interest, Kate (played by Frances O'Connor), decide to travel back in time to rescue him. They are accompanied by two other researchers, Andre (played by Gerard Butler) and Stern (played by David Thewlis), who have more experience with time travel.
When they arrive in the past, they discover that the region is in the middle of a war between French and English forces. They must navigate the dangers of this time period, avoid getting caught in the battle, and find a way to rescue Johnston before the wormhole collapses.
As they journey through the past, they encounter knights, archers, and other medieval characters. Along the way, they also learn about the political and cultural differences between the past and present, and how their actions could impact the course of history.
Ultimately, the group succeeds in rescuing Johnston and returning to the present day, but not without some casualties and sacrifices. The film ends with the team reflecting on what they've learned and how their experiences have changed them.
