An unexpected, early Christmas gift from an old friend awaits Ben and Rachel. It is nothing much; just a sloppy handwritten card and a suspiciously light cardboard box wrapped in cheap paper. However, the present comes with a strange yet strict rule: no matter what, the couple must never leave the package unattended. It sounds peculiar, or even unsettling, but by the end of the night, Ben and Rachel will wish they had never accepted the mysterious offering.
