Basically as others have said, it's a time capsule of Punk Rock at the time. While it's nice to see some familiar faces in their formative years like Billy Idol, The Clash etc it's mostly unknown bands from the time. If you're expecting to see The Sex Pistols in all their glory, you'll be sadly disappointed as theres a small bit at the start. Probably the most interesting part is The Clash being taught to play Reggae. But mostly clips of bands playing extremely bad and fly on the wall interviews. The footage is also pretty bad and hard to makeout faces sometimes.
Worth a look, although you'd only watch it once then move on.
