A couple ask Ben to be their sperm donor; Mark shows up and wants to be a part of Kenzo's life; Abi becomes upset with Roger when she dreams he cheated on her.

Ben talks Roger into helping him move the body of a patient who died in his dental chair; Abi and Susan suspect Roger and Ben are having affairs.

Susan wants to renew her wedding vows with Ben, which is no problem for him, until he is given director's tickets for a football match on the same day. Meanwhile, Janey is trying to get Kenzo into St. Justin's school.

Michael succeeds in placing the whole family on "The Weakest Link", but Anne Robinson is about to raise more difficult questions than expected.

Roger's mother visits London to meet future daughter-in-law, Abi, and an old drinking mate from Ben's youth has changed much more than he had expected.

It's the day before Roger and Abi's wedding, but for this accident-prone couple, anything that can go wrong probably will, before the marriage is solemnized.

Some old friends of Susan and Ben are having marriage trouble, and Susan is out to prove that a trouble shared is a very dangerous thing. Elsewhere, Janey and Kenzo are trying their hand at fame.

Susan is accused of shoplifting, and as if the forgetfulness, mood swings, and night sweats weren't enough of a problem, she also has to put up with Ben defending her in court.
