She will have to contend with the salon’s high-maintenance staff – her family. Family feuds and bitter rivalries, professional and personal, escalate in the salon amongst the Botox, fillers and face-lifts.
When Bel and Wesley's kids go off to university, best mate Teddy - who is in love with Bel despite being married to her sister, Leanne - puts in motion a plan to break up their marriage.
Bel hopes Wes's infidelity will be short-lived and puts a plan in motion to win him back. She books a PT session with Lorelei and is horrified that her rival is young and gorgeous.
Bel plots to humiliate Wes and Lorelei in front of their friends and family. Meanwhile Leanne is trying to get one up on Bel and has organised a billboard to promote the salon. Bel and Chizzler have a heart to heart where Chizzler tries to get her to talk to Wes.
Lorelei tries to win Wes's heart, and while he wants to end his affair with her, Bel's head is being turned by Teddy. Leanne has organised for MirrorBel salon to have a stand at an anti-ageing fair. When Bel, Tina and Heidi turn up, they're surprised to discover that Leanne is promoting herself as a guru for the genre. It's clear that beyond designing the packaging, she doesn't have a clue what she's doing. Later, Teddy tells Bel he'll invest in the business as long as they keep it secret from Wes and Leanne. Drama, starring Polly Walker and Robson Green.
