 Arnie watches the animal seller s van leave, then hears Sam pounding at the door of the garage, where he is now locked in. Sam tells him to get onto the roof, where s there s a skylight. Inside are a number of puppies. Sam piles up some boxes, and Arnie helps him out, but as Sam climbs, he kicks over a foul-smelling tin... Arnie and Sam head home to get a rope ladder. They have no trouble in freeing it from the tree, but then there s a problem of Arnie s nosy sister, Jessica, and his father, who won t let his son go off again. Sam heads back on his own, now with a torch. Sam climbs down inside the garage, but the puppies aren t moving... Then, he hears the van returning, and in tears, climbs back out to the roof - in his haste his wristwatch comes off, and falls to the floor. The man comes in, notices the poisonous fumes, and without noticing it, steps on Sam s watch. From the roof, Sam looks on, appalled, as the animal trader lobs a sackful of dead dogs into the canal. Then he hears the man make a call in which he explains the loss as an accident caused by the puppies, and asks for two more dogs to be delivered. At school the next day, Arnie is surprised when Sam turns up with a dirty great clock hanging round his neck - he explains about the loss of his watch. Others in his class look at his clock as though it is a fashion statement! Mr. Robson arranges to have a meal with Martha. Mr. Brisley throws a random suggestion to Martha about the drama group which she takes up - making the Romeo and Juliet play contemporary. Anna tries to poke her nose into Arnie and Sam s business, but they aren t in the mood for her. The drama workshop seems full of tensions and arguments, with Anna demanding participation, Joe s girlfriend Paula looking daggers at Jessica, and Brian sulking because Jessica insulted his acting abilities. Martha suggests an improvisation session. Unfortunately some personal comments are made, Joe takes what s said to heart, and decides to leave, calling upon all his friends to go too. Before she knows it, Martha finds that the drama workshop consists entirely of females! After school, Sam demonstrates fishing to Arnie on the canal bank, and discuss their plans to thwart the animal seller. Nearby, Jacko walks with Becky, discussing their intended seaside trip. Mr. Robson is strolling out with Martha Jordan, but to their annoyance they find Grange Hill students everywhere they go. As Martha kisses Mr. Robson, on the other side of the canal Arnie tugs his fishing line - a master fish, he announces, as he pulls up an old boot!
