An elementary teacher during the school year, Lily Grayson hires out as an au pair during the summer order to travel expenses-paid to exotic locations with wealthy families with children. When one of her students suggests she apply for a summer job with his family going to Costa Rica, she jumps at the chance. Despite her immediate clash with his father, she agrees to accompany him and his two children to the central American country.

Rich Texas rancher, originally from Costa Rica, Antonio "Tony" Delossantos, knows money can't buy everything. He lost his wife to violence and he's determined to save his children from a similar fate. He learns his son's school teacher is skilled in Krav Maga military-style self-defense and available for the summer. Tony hires her to accompany the family to Costa Rica.

When the drug lord Tony helped send to prison escapes, what started as a summer vacation in a tropical paradise soon becomes a race to survive in the jungles of Costa Rica.
