The Mark of the Berserker (TV story)

The Mark of the Berserker was the fourth story in the second series of The Sarah Jane Adventures. Clyde Langer's family appeared for the first time and it was the first story to have Sarah Jane Smith in a cameo role.

Synopsis
An alien pendant which gives its wearer the power to control others is stolen from Sarah Jane's attic. Luke and Rani enlist the help of Clyde's mum to track down Clyde and his father, who has the alien pendant. The chase leads to a terrifying waterside confrontation when the pendant takes control of Paul and begins transforming him.

Part 1
Rani walks by the detention room at school. She witnesses a boy, Jacob West, controlling his teacher and fellow students. He runs into the boy's bathroom, drops a strange pendant on the floor and leaves. Rani picks up the pendant and pockets it. On Bannerman Road, Rani and her father, Haresh, are deciding on tea and choose to have a pizza. Rani discovers that Haresh will follow her verbal instructions. She deduces that the pendant causes people to follow instructions given to them by the pendant's wearer.

The next day, somebody knocks on the door of the Langers' home. Clyde answers it and finds that his long-lost father, Paul Langer, has turned up. His arrival upsets Clyde and his mum.

After an emotional discussion among the three of them, Clyde leaves with his father. During the course of the day, Clyde reveals to his father that he is involved in tackling alien threats. Meanwhile, Rani goes to Sarah Jane's attic and puts the pendant there so no one will find it. After a talk with her father, she decides to investigate matters herself. She finds Luke, and they go to the school to search for clues.

Clyde convinces his father that he is telling the truth by taking him to Sarah Jane's attic. Paul finds the pendant that Rani left and puts it in his shirt pocket. Ourside they meet Haresh, who asks them about what they were doing in Sarah's house. Paul ends up instructing Haresh to do press-ups and realises it must be due to the pendant. Luke and Rani run up to them. Rani works out what has happened and confronts Paul and Clyde. Paul instructs Clyde to forget who Rani and Luke are. They walk off. Paul finds his hand has a strange symbol on it.

Part 2
Clyde and Paul are walking in town. Paul can't stop looking at the symbol on his hand. Luke and Rani attempts to contact Sarah Jane, but she is preoccupied trying to pursue an alien called Travist Polong. Meanwhile, Luke and Rani send a picture of the pendant to Maria and her father to investigate, as her father can hack into UNIT. They discover the pendant can cause a symbol known as the mark of the Berserker to appear on one's skin.

Haresh refuses to stop the press-ups. Paul gets everything he wants for free (including a new car), and uses this to bond with his son. He instructs Clyde to forget about how he left him and his mum when he was young and to forget about his mum. The pendant takes over Paul's skin and he collapses. He declares himself the Berserker and Clyde his soldier. Sarah Jane appears and Clyde recognises her. She tells him that his mum, Rani and Luke are the most important in his life when he asks who they are. Clyde and his mum talk Paul through his memories, whilst Sarah Jane shows him a reflection of himself in the mirror and he remembers who he really is.

Everyone the Berserker commanded has their commands undone. Clyde tries to get his mum and dad back together, but Paul tells his son that he has made his mum's sister pregnant. Clyde tells his father he doesn't need him and not to mess up with this baby. Clyde tells his mother to forget about the pendant, what she knows about Sarah Jane's adventures with her son, and his father, then throws the pendant into the sea. Sarah Jane reveals that her parents died when she was young and she would do anything to see them again. When Clyde is gone, she takes out a picture of her mother and father and rubs her finger over the latter.
