A BBC adaptation of the Victorian "penny dreadful" tale of 19th century "demon barber" Sweeney Todd, of Fleet Street, who cuts the throats of unsuspecting clients in his London shop.

In 1846, Anthony Hope sails into London with the mysterious Sweeney Todd, a once-naive barber whose life and marriage was uprooted by a corrupt justice system. Todd confides in Nellie Lovett, the owner of a local meat pie shop, and the two become partners, as Todd swears revenge on those that have wronged him and decides to take up his old profession.

Aging local standup comic Sweeney, "The Character King", gets an opportunity to do a national cable show out of Los Angeles. The only caveat is that Sweeney must drop the locally referenced material from his act, the biggest pieces being the portrayal of his colorful Boston "characters," that have become a staple of his home field success. Sweeney makes the hard decision to stop doing the characters. But, to his dismay, the characters "come-to-life" and seek their revenge; they try to kill Sweeney.

he Sweeney is a British television police drama focusing on two members of the Flying Squad, a branch of the Metropolitan Police specialising in tackling armed robbery and violent crime in London. The programme's title derives from Cockney rhyming slang, in which the expression Sweeney Todd rhymes with (and stands for) 'Flying Squad'. 　　The programme, made entirely on film by Thames Television's film division, Euston Films, was originally aired on ITV between 1975 and 1978, starring John Thaw as Detective Inspector Jack Regan and Dennis Waterman as Detective Sergeant George Carter. Such was its popularity in the UK that it spawned two theatrically-released feature film spin-offs, Sweeney! and Sweeney 2.

Jack Regan, an unethical officer of the Flying Squad, uses unorthodox methods to pursue criminals with the help of his partner, George Carter.

When his peeping passions become compromised, Todd decides he’ll do whatever it takes to continue stalking his beloved Claire. An obsessive HOA fleet and a dense boyfriend are obstacles Todd must dance around if he wants to sing his way into Claire’s heart. As Claire gets wrapped up in the lies of her fiancé and the web of her stalker, she must escape the two most toxic relationships she’s ever faced.
