The Timewasters gang are back for more time-busting adventures. This time, the South London jazz band are transported back to the 1950s.

Nick is a jazz man in a golden age of jazz. But the more he tries to make a name for himself, the more his schemes run into trouble: his musical hero turns out to be a dirty old man; he nearly stops Ronnie Scott from opening his legendary club; and his attempts to save his own jazz club from closure lead to somehow turning it into a strip club and later into sparking a fully-fledged race riot.

Meanwhile, Jason is over the moon to rediscover his one true love from the 1920s. Victoria is now in her fifties with a 32-year-old son: Jason Junior! Is it finally time for Jason to grow up and become a dad? Lauren is on a roll with more get-rich-quick schemes, but finds herself getting the hots for Jason Junior – much to Jason’s horror.

Horace however has no trouble making post-war London his home. He joins a West Indian Church, and then becomes a Teddy Boy. He even briefly has a stint in the limelight as a celebrated author. But in an era of Cold War paranoia, Horace begins to fall for a woman who is also a Russian spy. Will their love triumph over her need to report him to the KGB? And with the KGB on their tail, will the band get out of the 1950s alive?

Timewasters is a half-hour comedy about a struggling four-piece South London jazz band who travel back in time to the 1920s via a urine-sodden lift in a dilapidated block of flats.

Stuck in the past after their ‘time machine’ malfunctions, our gang decide to explore Edwardian London, before quickly discovering that being young and black in the Jazz Age is a lot less genteel and a lot shadier than Downton Abbey had led them to believe.

Aided and abetted by a pair of oddball twins and some 1920s luminaries, the band are forced to navigate the parties and pitfalls of the Roaring Twenties while searching for a way back home.

Cue our heroes getting thoroughly stuck into 1920s life: trying to become the first black Queen of England, joining a eugenics cult, potentially ruining the invention of television, repeatedly falling in love, getting married, and playing brilliant jazz versions of the 21st century’s greatest songs to an equal parts baffled and delighted 1920s crowd – from Back to Black to Hey Ya via Return of The Mack.
