Spencer and Julia are a married couple in a rut. To get their relationship back on track for Valentine's Day, Spencer sets them up with a very special spa day, full of massages, pedicures, and the spa's signature...and airborne aphrodesiac guaranteed to put its customers in the mood for love. Things get complicated when a storm strands everyone in the spa longer than expected and horny staff members start wanting Spencer and Julia's sexual affection as well.
