If you are looking for a plot synapses, there isn't one. The movie is one giant chain reaction. There are a lot of running jokes, each building up to a hilarious climax of absurdity. Hasselhoff spoofs himself amazingly well. I was never a Baywatch or Knightrider fan, so whatever inside jokes there were about those series was lost on me. However big Hasselhoff fans I'm sure would enjoy the movie even more. The movie takes a lot of pokes at Hollywood, adventure movies, PC culture, LA culture, even Ted Nudgent. Does so not in a mean spirited way though. It's sad that the craft of comedy has fallen so silent. Basically hour and a half fart jokes is what most comedies are about. This one offers plenty of slapstick but also more subtle jokes. Most of all it has a Robin Williamsesqu love of how absurd life is. In the end it's just fun. No politics, no preaching, no agenda, just a fun time and plenty of laughs.
