After one of his countless mishaps, Félix (Felix in the English version), a clumsy and unlucky Iberian lynx, is transported to the animal recovery shelter at the Doñana National Park, along with Beeea (Beeety in the English version), a daredevil Iberian ibex, and Astarté, a brave peregrine falcon with an injured wing.

While the others are skeptical of Gus' claims, a female lynx, Lincesa (Lynxette in the English version), is brought to the shelter; she and Félix begin to form an attraction to each other.

Due to the antics of two bumbling mercenaries, Félix is able to escape from his cage and free his friends from the transport trucks, with the exception of Lincesa being hit with a sedative dart by Newmann.

With some encouragement, Astarté is able to fly back to the shelter and set off the alarm, alerting the humans to their disappearance.

They meet Diogenes, a vulture with a mission to clean the environment, who supplies the group with materials to build a makeshift transport to outrun the mercenaries.

He tells her that he was once locked up in an insane asylum for claiming to talk with animals, but after being released, he used his communication skills to amass a large fortune (e.g., horses at the racetrack, moles finding oil pockets underground, fish guiding him to sunken treasure).

His plan to collect endangered animals and bring them to an island refuge is his way of thanking them by saving them from extinction, for helping build his fortune.

Realizing that it's not his bad luck to blame, Félix returns to his friends in time to save them from being caught by Newmann.

Unexpectedly, Newmann causes an explosion that starts to flood the ship, beginning an evacuation protocol of the caged animals.

In March 2005, Raul Garcia and Manuel Sicilia were hired and set to write and direct The Missing Lynx.

Antonio Banderas, Marcelino Almansa, Juan Molina and Manuel Cristobal produced the film with the budget of $6,500,000 for release in 2008.
