Linda is asked for advice on a disturbing case being investigated by old friend DI Angie Morton, and looks to husband Richard for support. However, she is forced to deal with a sexual problem of her own when he delivers devastating news - and it appears the solution may lie with Richard's brother Greg, though his wife Penny is unsure about letting him step in.
Richard is released without charge, and Linda is furious with him for meeting up with Claudie behind her back. Back at the practice, the therapist offers advice to a man whose wife is addicted to Internet pornography, while Greg sees a couple having problems with impotence. Later, a friendly barbecue is spoiled when Linda's clients' problems return to haunt her.
