The Secret Teacher - Season 1

First up is marketing mogul Paul Rowlett, working at a Hertfordshire secondary school. With a business that turns over more than £20million a year, Paul is searching for students who can use his money to help.

Liverpudlian millionaire Kate Stewart leaves her property empire behind as a support worker in a school in a deprived area of Sheffield, confronting the realities of the students' daily life. Her attention is caught by 15-year-old Zain, whose disregard for the rules has brought him close to expulsion - will Zain's entrepreneurial efforts at the school fundraiser be enough to impress Kate?

Despite being expelled from school at 15, Steven Bartlett runs one of the biggest social media marketing companies in the world, turning over millions of pounds a year. Now he goes undercover at Litherland, a cash-strapped school in Liverpool. During his six weeks, Steven meets Eloise, whose casual attitude hides a difficult past, and Ste, who dreams of becoming a millionaire. Steven also wants to use his own experience to help improve the mental health of staff and students, but how will headteacher Mr Rodgers respond to the newcomer's ideas?

Darren Ryemill, the owner of an award-winning recruitment agency, goes undercover at the all-boys Forest School in Wokingham, Berkshire. He is shocked by the building's state of disrepair, with peeling paint and leaking toilets, and school head Ms Austin is forced to remind Darren that he cannot fix it all. He focuses his search for students in the school's Return to Learn initiative, where boys are sent as an alternative to exclusion. He meets 15-year-old Levi, who spends much of his time out of lessons. But a heart-to-heart with Darren reveals there is more to Levi's behaviour than first meets the eye.
