The first in a new series, 'Four Seasons,' takes us to Deepwater Cove, a small community on the shore of the Lake of the Ozarks, where we're introduced to four couples in different stages of life.  It Happens Every Spring centers on Brenda, a lonely wife, and Steve, a go-getter real estate agent, in the mid-winter of their relationship.  When a stranger appears at their door one night, change blows through their house and their marriage.
