"Hot Snow" is the debut episode of the 1960s cult British spy-fi television series The Avengers, starring Ian Hendry and Patrick Macnee.

Dr. David Keel's (Ian Hendry) fiancée and surgery receptionist Peggy (Catherine Woodville) is murdered by a ruthless gang of drug dealers.

It has been released on DVD as a bonus feature by A&E Home Video in its Emma Peel Megabox collection, alongside the two complete surviving episodes from Season 1.

The episode and series is described by Anthony Aldgate as being "conceived within the discourse of psychological realism that informed most contemporary television drama.

It set up a motivation for the hero-figure of Keel, described by Hendry as 'a most attractive character [who] combines toughness with compassion and serves as the conscience of the team'.

However, whereas Bond traveled to exotic foreign locations in his pursuit of international super-criminals such as Dr. No or Goldfinger, The Avengers was concerned mainly with home-grown criminals whose ambitions (at least to begin with) were somewhat less grandiose.
