Samantha "Sam" Monroe hoped for a quiet weekend in Vermont as a bridesmaid at her brother's wedding. She looked forward to escaping her complicated life in Boston, where her estranged partner is in a coma and her former best friend is in jail awaiting trial for attempted murder. But things get complicated: her boyfriend is also her bodyguard, her family is loving but overbearing, the bride wants everything to be perfect, the father of the bride is missing, a local car dealer is involved in drugs, and a dead body turns up in the snow outside the church.
