In the middle of winter, when the cold is at its peak, here come girls who've just returned from enjoying the sun in the tropics! They appear on a fictional show called "Find the Tanned Beauty!" and, invited by MM, indulge in exercises like "Twister" and "Limbo Dance" to show off their tan lines. As they enthusiastically chase the prize money, their healthy, sun-kissed skin and bikini-clad bodies, accentuated by striking tan lines, radiate a more erotic charm than fair-skinned girls ever could.
