Timewasters is a comedy about a struggling four-piece South London jazz band who travel back in time to the 1920's via a urine-sodden lift in a dilapidated block of flats. Stuck in the past after their ‘time machine' is destroyed, our gang decide to explore, before quickly discovering that being young and black in the Jazz Age is a lot less genteel and a lot more shady than Downton Abbey had led them to believe.
