Skin Deep (1978)

In small town Carlton Bob, the head of the Progressive Association, the local accountant and the boxing coach at the men-only gym, hires a masseuse from Auckland. Sandra is quite happy to give straight massage, but Bob pressures her to give "city massages". The wives are disturbed by her presence - perhaps with some justification. The climax occurs when accountant Phil, wants to leave his wife for Sandra; but when she rejects him, he smashes up the gym. The boys rally round to hush up Phil's indiscretion.
