Sweep has sent out a letter to all his relatives asking them to come round to Sooty's House for a big family reunion. He receives only one reply, from his long lost brother, Swoop, who also sends them a picture of himself so they know what he looks like. However, Matthew thinks that Swoop has accidentally sent a picture of Sweep by mistake, as he looks exactly like him.
Meanwhile, Sweep is getting ready for his brother's arrival in the bedroom by trying on his new blue collar. Suddenly there is a knock at the door. Sooty and Soo watch as Sweep leaves the room to answer it and then seemingly comes back with a different collar. This however is Swoop, who has let himself in without seeing his brother. The two dogs keep appearing and disappearing alternately, confusing Sooty and Soo until they both reappear again together.
In the bathroom, Sweep and his twin brother, Swoop are playing around with Sooty and Soo in trying to make them guess which ones which, when Sweep's cousin, Swipe arrives and makes it even more complicating.
Later on downstairs in the kitchen another of Sweep's cousins, Swap arrives and Matthew decides to organise a celebration party for them all. During lunch, an entertainagram arrives with a message from Sweep and Swoop's parents saying that they will be here soon. This entertainagram also entertains with the art of making balloon animals.
Back in Sooty's bedroom, Sweep is very excited because Matthew has allowed Swap, Swipe and Swoop to stay the night. Then Sweep's parents arrive along with his seven other brothers. Sweep's family all have a happy squeaky party in the bedroom, so Sooty and Soo go to bed in Matthew's bedroom for the night.
