แผนของพ่อเลี้ยง: ประสานลูกพี่ลูกน้องให้กลายเป็นความสนิทสนมอย่างเข้มข้น

Lily and Oliver's relationship is at its worst. The two stepsiblings are constantly fighting and their stepmom, Sandy, has had it with their rows. Fed up, she comes up with a couple of tricks that will help them get along. From tying them up to making them wear one big undie together, Lily and Oliver slowly start to become closer…perhaps too close!
