A hypnotist is booked to provide the entertainment at the triplets' baptism - and Agnes soon finds herself under his spell. Meanwhile, the matriarch's kitchen is falling apart - but that turns out to be the least of her problems when son Mark delivers some heartbreaking news.

Agnes is disappointed with Cathy when she decides to get a boob job to impress her boyfriend, Professor Clowne. Agnes is also distinctly unimpressed with Buster when she meets the man he has hired to measure up her kitchen. Meanwhile, Professor Clowne has a life-changing proposal for Cathy - if he could only find the perfect moment to ask her his very important question.

It seems that everyone in the Brown family has a date for Valentine's Day except Agnes, so she resorts to the internet to find herself a man. Dermot tries to come up with a loving gesture to prove to Maria that he can still be romantic - but he makes the mistake of taking advice from Buster - while Agnes and Winnie are fascinated by Betty's sex manual and Grandad ends up addicted to Viagra.

A secretive phone call from a solicitor to Mrs Brown leaves her children suspecting one of them may be adopted, while Father Quinn returns from rehab and asks Agnes to help out at his annual garden party - although as she proceeds to drive him crazy with a smartphone, his recovery may be short-lived. Meanwhile, Cathy receives a blast from the past, Rory and Dino have a bust-up, and Mark and Betty deliver bad news - they are leaving for Australia right away.

The Browns are excited as preparations for Rory and Dino's big day are in full swing - although Agnes's mood is dampened when she meets flamboyant celebrity wedding planner La La Doggy. The foul-mouthed matriarch also clashes with Father Damien when he raises some religious concerns about the ceremony - and to top it all off, she gets more than she bargained for when she invites Cathy's boyfriend's parents over for the evening.
