Its almost monotonous - the BBC Restoration Team have performed an excellent transfer to DVD. Both picture and sound quality are excellent. There is nothing to show that 27 years separate the original production and this release - it looks as good as new.

Three lighthouse keepers prepare for another evening's work. Vince, the youngest, watches a streak of light as it falls from the sky and into the sea. Soon after, a strange fog encompases the local sea and the isle upon which the lighthouse stands. The electricity that powers the light begins to behave oddly. Ben, the head lighthouse keeper invtesigates but is killed by something hiding in the coal cellar.

The Doctor and Leela have fallen short of their planned visit to Brighton. Curious about the dim lighthouse, the travellers are caught up by the events that unfold. With the electricity continuing to act erratically the light fails and a ship crashes upon Fang Rock. The survivors are brought into the lighthouse. It is not long before they find themselves at the mercy of a hostile alien that is killing them one by one.
