The series started on October 3, 2010, and the finale, which took place in Campo Pequeno, Lisbon, was on December 31.

The show lasted three months and was hosted by Júlia Pinheiro, Pedro Granger, and Leonor Poeiras.

[citation needed] The eviction shows (also called Galas) took place on Sundays and a daily diary of what happened in the house was broadcast on the other days of the week.

Since November 15, another hour of Secret Story began to be broadcast in the late afternoon, therefore making three programmes per day plus a 24/7 channel.

[citation needed] The format is based on the French one, although the Portuguese version has more secret missions.

[citation needed] Ana Isabel Ribeiros was 26 years old when the series began and lives in Guimarães.

Hugo F. told Ana Isabel he knew her secret in week 2 but didn't have the courage or money to reveal it.

In May 2011, she participated in the second season of Les Anges de la télé-réalité, which was set in Miami.

In this game, there were eight other former candidates for reality TV, including Jonathan, her former boyfriend of Secret Story 3 in France.

She appeared shy on the show, but she mentioned she acted that way so that her boyfriend (in the real world) would still love her.

Although at first, she intended to "declare war" on Ana Isabel, after Vítor's ejection all the housemates became closer, and the two developed a friendship.

Mário Lima is 26, lives in Pontinha and his secret is that he is Renato's twin brother.

His secret is that he was Mario's twin brother, which was discovered on day 2 by Ana Isabel.

His secret is that he is the son of a public figure, António Luís Alves Ribeiro Oliveira.

She told her secret to other housemates on Day 22, without revealing it was hers, but still, she was punished by losing all her account money.

Secret Missions, Tasks & Accounts: Mário and Renato are twin brothers.

While one is open in the house, the other is hidden in a secret room, and they periodically switch places, both going by the name Renato.

Nominations: Mário and Renato were automatically up for eviction since Ana Isabel discovered their secret on Day 2.

Secret Missions, Tasks & Account: Zé Miguel had to steal Jade's Yoda doll—a McDonald's Happy Meal toy similar to a Magic Eight Ball)--and incriminate Ivo.

Vasco thought that Ana Isabel's secret was that she lived 9 years in a convent.

In a strategic move, Hugo M. pretended to discover Joana's secret, claiming that she is the accomplice of "a Voz".

Some people threw tennis balls to the garden with information about Ana and Vitor's secret.

Secret missions, Tasks & Accounts: On Day 22, all the housemates began a group challenge of remaining 50 hours on a stationary bike.

For the shopping task, to earn time in the storeroom for food, several personalities were displayed on the living room television.

Renato discovered Vítor and Ana Isabel's secret on Day 25 and so all their money was transferred into his account.

Zé Miguel had a mission to convince the other to take part in a Portuguese folk dance class.

Nominations: The phone rang on Day 29, and as Andreia was the first to answer it she won immunization for the week.

He passed the task and won not only €5000 as also he spent an entire night with Ana Isabel alone in the secret room.

For the storage task, housemates will write "Secret Story" with some dominoes; the larger the number of pieces that stay up, the more time they win.

In that second round, Vítor and Zé Miguel tied again with 2 votes and therefore were both up with Hugo F. Exits: Vitor was ejected on Day 54.
