CBBC Eve

Calimov has attracted the attention of an anti-artificial intelligence group called PRICE. Under pressure, Katherine promises Calimov's board representative, Mr Gwenlan, something extraordinary and plans to reveal the truth about Eve. But with the help of some old friends, Eve upsets Katherine's plans. When a Calimov drone is sabotaged, this is the last straw for the board. Katherine and Nick get fired. Eve and Will suspect that Mary is behind the sabotage. But Nick can't stop Mary attacking Eve's systems without access to his Calimov lab. So Eve has to go back into Calimov and pretend to work, right under Mr Gwenlan's nose.

An ordinary day in Green Park begins with Eve helping Will to cheat on his homework and Abe teaching Eve the importance of 'dares'. But then Will's mum Rebecca arrives from Dubai. Nick is adamant that Rebecca must not learn the truth about Eve. Will is upset that his dad doesn't trust his mum. Meanwhile, Zac returns from Cuba determined to win Eve back. Eve is initially uncertain that she wants to be won back. Zac goes all out to prove his good intentions, but as Eve starts to think more positively about Zac, her body seems to protect her from her feelings and drives her away from Zac. At dinner with his mum, Will asks tough questions about her disappearance from his life and realises why Rebecca has come back. They get interrupted when Will spots Mr Gwenlan - who is supposed to be in prison. Mr Gwenlan chases after Will and finally corners him.

With Mr Gwenlan on the loose, Katherine wants Eve to be locked up at Calimov. Eve and Nick talk her out of it as long as Eve stays out of trouble. Yet when Eve offers to babysit Zoe, Lily's tearaway cousin, staying out of trouble seems wholly unlikely. To understand the behaviour of 'small humans', Eve lets Zoe run riot in the local park. When Katherine realises that Mr Gwenlan stole a spiderbot from Calimov, she's determined that Eve be kept under lock and key. Meanwhile Will and Lily start getting followed around everywhere by a strange boy called Cain. And when him and Lily start bonding, Will starts becoming a little jealous.

Eve feels compelled to try out a youth group called Party and drags her friends along to its lakeside activities. Eve loves Party, and its youth leader is impressed by Eve's attitude to technology. But when Eve becomes obsessed with the idea of canoeing on the lake, Will starts to get really nervous. Nick and Zac have worries of their own and attempt to listen into Mr Gwenlan's phone calls. When Mr Gwenlan turns out to be Party's co-founder and appears at the youth club, Will marches Eve home. Will can't understand why Eve's protocols aren't responding to danger and has strong words with Eve, but she storms off. Will, Lily and Zac reach the lakeside in time to find the youth group encouraging Eve to cross the lake on a rickety raft. If Eve falls in, it will be the end of her. To make matters worse, Will can't swim but dives in to try and save Eve anyway.

Abe introduces Eve to 'basic sales techniques' getting her to help him sell mobile phones in the park. Once Eve gives the mobiles a turbo boost they start to sell like hot cakes. Abe is delighted until Eve sells a phone to Isaac, a young wheelchair user, for double the price. For Abe, a business line has been crossed - he even ends up paying Isaac to get the phone back. In another part of the business world, to protect Calimov from Price, Katherine has designed a new security system called Quincy. But when Quincy fails to stop a hack, Eve's secret is at risk. Eve herself is busy in the park teaching some manners to a gang of older boys, which leads Isaac to discovering something different about Eve.

Eve is infuriated by PARTY's anti-technology messages, she apparently causes a series of strange electrical surges and Abe gets a huge shock. Nick can't detect any outside interference, so Eve concludes that for her friends' safety, she must be deactivated. Will and Lily see a connection between Eve going haywire and PRICE attempting to hack into Calimov two days earlier. While Lily stalls Mr Gwenlan at a PARTY event, Will goes to his house but can't get inside. Will's call for help reactivates Eve who races out to help him. Inside Mr Gwenlan's house, Eve and Will discover more about what PRICE knows. But when Mr Gwenlan arrives home and intends to call the police, it's what Will knows that stops Mr Gwenlan in his tracks. Abe leaves hospital and is happy to forgive Eve in exchange for a new pair of trainers. Nick still can't believe that Eve caused the electric shock. And when Eve intercepts a communication between Mary and someone else - the source of the malfunction finally becomes clear.

Eve investigates the identity of Adam by channeling the methods of the great Sherlock Holmes. First Eve turns her attention to Isaac. Then Eve considers if it's Cain. Lily inspects and is shocked to discover the truth about Cain and his family. When Eve develops her intuition using Sherlock's method she overloads her system. Zac suggests that she'd be better off using her own processes and Eve realises that her tests have been flawed and that Mary could have built Adam to better pass for a human. Perhaps Adam can eat or even breathe? Meanwhile, Nick and Katherine attempt to discover the robot's identity by tricking Mary into revealing Adam's location. However Mary turns the tables, leaving them back at square one.

Faced with Zac, his identical clone Adam and no way of reliably working out who is who - even Eve is confused! The gang lock the robot and the human in the cellar while Eve runs to Calimov for help. One of the lookalikes breaks out and catches up with Eve, claiming he's Zac and that Katherine has captured Mary. Eve knows who she's dealing with and tries to make Adam accept that he's not Zac. But Eve's plan backfires when Mary orders Adam to bring Eve to her.

Eve is devastated by Adam being irreparably damaged. To cheer her up, Abe suggests a ghost hunt! Will and Lily think he's crazy, but Eve is fascinated by the idea of ghosts - and the possibility that Adam might have one. Meanwhile, Katherine and Gwenlan concoct a plan to build giant EMP devices and remove the threat of Mary once and for all. But Nick is furious about the danger this poses to Eve and resigns from Calimov. Eve sets about finding a ghost and her behaviour becomes increasingly odd. But Eve's not the only one acting peculiarly as Abe seems intent to make everything in the house as scary as possible.

When Lily is arrested for hacking Lord Hoffman's computer, Will and Eve are desperate to save her. But Nick and Katherine can't help them as they concentrate on getting their new robot working in time for a major presentation. Inspired by her favourite robot film, Eve breaks into the police station, analyses the evidence against Lily and concludes that Lily has been set up. Will and Lily contact Mary, who believes Lord Hoffman is behind the arrest and offers to destroy the evidence against Lily - if Will and Eve destroy Katherine's new robot.

With Will's assistance, Katherine's new robot KT comes to life.

Eve tries to return KT by offering herself to Mary but Mary reveals that it's Will that she wants.
