Plot
German auditor Lilli Funke travels to Mallorca to visit her younger sister Valeria "Valle". There, she soon learns she is engaged to Frenchman Manu Chassée, whom she met four and a half months earlier, and they are planning to open a bed and breakfast (B&B) together. In a nightclub, Lilli meets bartender and club manager Tom Sommer, also from Germany. The two begin an affair.
Valle and Manu want to buy his uncle's property for the B&B. She has €40,000 for this from her mother's inheritance, money originally intended for her university education. Valle also wants to sell the property she inherited from her mother, half of which is owned by her sister, who opposes the sale. Soon afterwards, Lilli meets real estate investor Nick Unterwalt, who offers €900,000 for the property.
Lilli's mother was from Mallorca and died when Lilli was 18, while Valle was 10. Manu's ex-girlfriend Bea suddenly shows up. Lilli discovers that Manu does not work at the Hotel Mirabelle as claimed and fears he is just trying to exploit Valle. He claims to have been made redundant when the hotel changed ownership.
Tom arranges for an appraiser, who estimates the value of the property at €700,000. He advises Lilli to accept Unterwalt's offer, and she agrees. When she has a broken water pipe repaired at the house, the repairman tells her it had been tampered with.
Lilli then visits Bea to hear her side of the story. Bea reveals that Manu has scammed her out of a lot of money and is now trying the same trick on Valeria. Lilli confronts her sister with the fact that Manu is a fraud, but Valle refuses to believe her.
Manu expresses his joy to Tom that the sisters have agreed to the sale to their mutual client, Unterwalt, and that he will soon be rid of Valeria. Through Unterwalt's employee, Lilli inadverently discovers the property meant for the B&B does not actually belong to his uncle and is not for sale. Furthermore, a luxury resort is planned for construction on their property, and all investors are already on board.
Lilli shows up at Unterwalt's eight-year-old daughter's birthday party at his estate, where she encounters Manu, Valle, Tom, and the "appraiser". Realising it has all been a scam, Lilli confronts Unterwalt with the fact that the property is worth far more than the €900,000 being offered.
In Tom's belongings, Lilli finds an envelope addressed to his real name, Tobias Winter. On his laptop, she also finds a folder marked "LF", containing documents and photos of Lilli and Valeria. When confronted with this, Tom asserts that not everything was a lie.
As Valle begins to have doubts about Manu, she visits Bea and finds her dead in a bathtub. The police suspect suicide. Meanwhile, Tom confesses to Lilli that he was responsible for the burst water pipe. He also orchestrated the theft of her handbag at the nightclub.
After Unterwalt puts pressure on his wife Girasol, she tries to force Lilli to sign the purchase agreement, while Manu threatens her with a gun. (It is apparent that Girasol is controlling the two male expats.) Tom surprises everyone by disarming him and jumps off a cliff into the sea with Lilli. The police, called by Tom, arrest Manu and Girasol.
A year later, Lilli returns to Mallorca, where Valle has since opened a B&B, and Lilli reunites with Tom.
