The adventurous youth series, made for kids aged 8 to 14, was developed by Lucille and produced under the Lucille Werner Foundation. The series follows a boy named Cappie, played by Tom van Hulle, who has a visual impairment that heightens his other senses. Together with his friends Sam, Ruben, and Charlotte, he forms a club called Caps Club.
Their clubhouse is an old treehouse, which their friend Siggy, who uses a wheelchair and is an inventor, modifies to make accessible for all members. The friends in Caps Club go on thrilling adventures and solve many mysteries.
The series contributed to the integration of children with disabilities.
Three seasons of eight episodes each were made, and the series has been sold to seven countries.
