Whilst looking for a bite to eat, the Doctor and Lucie arrive at a Motorway Service Station on the M62 during a terrible blizzard. Also en-route to the Service Station is star-making music manager, Arnold Korns, and his latest signings, Trisha and Tommy Tomorrow, ready to make their debut on Top of the Pops. However, outside in the snow and darkness is a dangerous threat - a pack of alien monsters that threaten to bring a sudden halt to the careers of these fledgling Glam Rockers...
The idea of a remote Service Station under siege by alien creatures is very reminiscent of the classic `base under siege' storylines that were used during the Second Doctor's era such as: The Moonbase, Fury from the Deep and The Ice Warriors. Unfortunately, the story doesn't have the benefit of a multi-part serial to build up the suspense and instead, throws itself straight into the action and is finished within the hour, which is the equivalent of a two episode storyline in the classic series. As a result the story felt like a mish-mash of `Classic Who' storytelling, mixed with the format and modern approach of the current series, similar to recent stories like Cold War.
We're quickly introduced to the cast of supporting characters: Flo, Pat, Arnold Korns, Trisha and Tommy Tomorrow, as well as a few extras who are effectively `Monster Meals' with several lines. Each of the characters was easily identifiable by their voices, which is something that can cause issues if several characters sound similar to each other. I really liked the character of Arnold Korns, played well by Bernard Cribbins who managed to chew on the audio scenery when on-air. While I wasn't entirely convinced by his change of heart mid-way through the story, I was impressed by Cribbins' acting range in playing a different character to the one he would eventually play on-screen (Wilfred Mott)
The tone of the story is hard to define as it's a strange balance of both comedy and horror with the unusual setting and references to 70's Glam Rock and the horror of bear-like creatures attempting to smash their way in and devour the humans inside. The death sequences seemed to be played for laughs with the over-the-top screaming and crunching sound effects used, along with the jokes prior to them, such as when Arnold observes Ron the Roadie making a run for it: "Maybe he'll make it" and then we hear the sound of crunching as Arnold adds, "But then again..."
Overall, this was a fun little adventure which took the Doctor Who trope of the base under siege and gave it an unusual setting in both time and space. The setting of a Motorway Service Station is really quite inspired as it is a very British tradition and evokes that feeling of isolation that a good 'base under siege' story needs. I also really enjoyed the Bowie-esque incidental music, especially during Arnold Korns' speech to the rampaging monsters as he stays behind to buy the rest of the group time - it felt very much like David Bowie's Life On Mars as the music swells.
