The calcium (as calcium carbonate) in hard water replaces the sodium on the fatty acids of the soap causing them to precipitate as a sticky scum. This deposits soap scum on the things being washed and causes the formation of "bathtub ring" on bathtubs, sinks, etc.

Soap is primarily sodium stearate. It leaves a film when it combines with hard water to form calcium stearate (soap scum). Body wash is a detergent that does not form soap scum.
