Sydney Fox is a professor and globe-trotting "relic hunter" who looks for ancient artifacts to return to museums and/or the descendants of the original owner. She is aided by her linguistic assistant Nigel and occasionally by her somewhat air-headed secretary Claudia. She often ends up battling rival hunters seeking out artifacts for the money.

A squadron leader and a retired milkman decide to bury their differences and move in together after they are both widowed on the very same night. They become a companionable if odd couple, until their unlikely friendship is threatened by the arrival of an alluring woman with a hidden agenda.
