The two former investigators Balko and Klaus Krapp return for the crime series "Balko Teneriffa": 15 years have passed since they were on the road together. While Balko sinks into great grief and a lot of alcohol because of the death of his wife, Krapp is doing great. He works in the Ministry of Defense and only travels in luxury jets. However, when he is accused of murdering a waitress who served at a party held by gun dealer Oswald in Puerto de la Cruz, he turns to Balko for help. Together they want to find out who is really responsible for the crime. But the local policewoman Alicia Ruíz is also investigating the case - and she doesn't like the fact that two German ex-cops are messing with her job.
