In this sexy comedy an affianced woman decides to sow one last wild oat before becoming a devoted wife. She therefore dresses up in a slinky black number and goes to her company Christmas party. The shapely lass impresses both her boss and a sales manager for the cosmetic company. The manager then sends her a new dress and she goes to his hotel room to have a little lunch. When he makes a pass, she flees and returns to the party and spikes the punch. When her fiance shows up, they all kick him out. Soon the drunken party-goers begin cozying up to one another. The girl realizes she has gone too far and sets off the company sprinkler system to sober them up. Things are suitably dampened and the partiers begin getting rather glum until they hear that one of the employee's wives has given birth. Later, the troublemaker makes nice with her fiance and they leave.
