Nicole (played by Helen Hartley) inherits Papa’s garage and decides it needs a trendy new image, so she sacks Papa’s greasy old mechanic — and advertises for a smart all-girl staff instead.
What she actually ends up with is Vicky Ford, Rachel Stevens, Samantha-Jane and Gill Sampson, who know even less about cars than she does, and with Papa’s ex-mechanic bent on taking his revenge as well, the scene is set for total mess.
Engine oil gets everywhere except into engines; their breakdown service just breaks down when Jo Bache finds herself waterlogged driving through a country ford and then contrives to mislay her car altogether in a mud hole; Police Inspector Anna Hay, losing her uniform if not her dignity, inspects the paint shop but wishes she hadn’t, and, when newcomer Joanne Roberts’s over-loaded catering van breaks down too, the girls show her exactly where to put her pies.
Following an ultra-steamy two-girl session in the shower, the finale’ finds everyone mucking in to help with varying degrees of success as resplendently gowned bride Karen Field gets her honeymoon car filled up all too literally while she’s still inside; at long last Nicole’s garage venture really goes with a bang — if not exactly in the way she planned.
