Meagaidh the border collie is a search and rescue dog who works with her owner, Tom. Her supernose follows scents and smells like clues so she can rescue people who need her help. Annie is in a kayak, but she doesn't have her map and is totally lost. She’s managed to paddle to a beach, but she’s cold and wet, and has hurt her wrist. At the Woofton Search and Rescue Centre, Tom and Meagaidh need to find Annie, and fast! At the beach, Meagaidh has to navigate the tricky terrain to help Tom find Annie and get her to safety. But first, she must filter out all the other smells – the sea, the sand, even a talking bin – so she can find Annie’s scent. Want to come along on Meagaidh’s Dog Squad mission? Then let’s get mission ready!
