Sink or Swim is a BBC TV sitcom from the 80s with Peter Davison as the lead character Brian Webber. Brian Webber lives in a flat above a petrol station in London (in the last series he moved to Newcastle to attend University). He's trying hard to make his way in the world, thus far with limited success. His girlfriend, Sonia, is a very serious minded young woman who is passionate only about things like vegetarianism and ecology. When Brian's younger brother, Steve, arrives in London looking for somewhere to stay, his lazy, cynical, noisy "Northern lout" attitude disrupts Brian's already messy life.
