Walsh Company.

While fourteen year old Duncan is being dragged on a family trip with his mom and her overbearing boyfriend, he finds a gregarious friend at a local water park. The two form a powerful bond as Duncan learns to swim through the challenges of life, love, family and friendship, resulting in a vacation he'll never forget.

Meet the Gallaghers. Mom went AWOL years ago. Dad stayed home with the six children only to hit the bottle, and sometimes the kids. The real head of the family is big sister Fiona, who looks after Carl, Debbie and baby Liam. She is occasionally helped, more often hindered, by streetwise "Lip" and the actively gay, but very private, Ian.
