The Cuckoo S01E04 - Episode 4

The drama builds to a deadly conclusion...

Sian is overjoyed as they drive but Alice is unsettled. Jessica breaks out of the cupboard informing Nick, who has arrived home, of Alice's kidnapping. Nick and Jessica track Alice's phone location. At a service station, Alice tries to send a message but Sian catches her and dumps her phone. Nick and Jessica arrive too late and discover that Alice was trying to send Jessica a text. They race to Aunt Fay's - their only clue to Alice's whereabouts.

Jessica and Nick arrive at the caravan park and start searching. They find Alice near a cliff edge. Jessica tries to reason with Sian, telling her that Alice isn't her daughter. Sian seems to grasp the truth but then charges at Jessica. In the struggle, Alice is pulled free by Jessica just as Sian drops off the cliff. They glance over but her body is gone…
