The Brits have a tv series set in Essex named "The Only Way Is Essex", and this Harmony Films feature steals its logo and otherwise trades on its local fame but with XXX content.
Misguided project is not even necessary, as a decade ago pornographer Phil Barry (porn superstar Cathy Barry's husband) in Bristol made a parody "The Only Way Is Sexsex" covering the same ground.
Hook is swingers, with strictly group sex scenes presented. Main swinger is played by Ian Tate, once known on screen as Dirty Dog, but lately in middle age using John Bishop as his screen moniker. He gets plenty of sex, while his wife, played by fake redhead Demi Delight, has orgies of her own.
Femme cast emphasizes big fake tits, and Antonio Black provides interracial sex, at one point servicing six ladies by his lonesome.
