Hearing dog Diesel is on an important mission - to wake his teenage owner Rayane, who's deaf, up in time for his football trial. There's a big match tomorrow, and Rayane really wants to be picked for the team. It's the summer holidays, so Rayane and Diesel have been sleeping in. Diesel needs to be on high alert!
Diesel's superears are trained to alert Rayane to important sounds he might miss. Diesel is Rayane's ears! In the morning, Diesel must filter out all the noises in the house and listen for Dad calling Rayane for breakfast. Rayane is being picked up for the football match by his friend Karim, so Diesel has to listen out for the knock at the door. Will his superhearing help him filter out all the other sounds and make sure that Rayane gets to his football trial on time?
