The Tunnel

The story takes place in the unspecified near future, though it is noted in the film that the Channel Tunnel is built "in 1940" Three years into construction of the tunnel, McAllan is a worldwide celebrity, but his work keeps him from his devoted wife Ruth and their young son. She is affected by an unknown gas afflicting the workers and loses her eyesight. Worried that her husband no longer loves her and not wanting him to stay with her out of pity, she leaves him.
