The highly skilled filming group known as Group H has consistently amazed viewers with a series of shocking hidden camera recordings. This past early summer, they planned to secretly film women changing into swimsuits shortly after the beach opening season began. After surveying locations nationwide, one member acquired ownership of a beach house, renovated it, and installed state-of-the-art hidden cameras in the changing room. Filming began on the Sunday just before the official beach opening, successfully capturing young, eager girls anticipating the arrival of summer.
