Watch FilmoFlix. 'Tup-Akka-Lakko' is a sequel to 'Koeputkiaikuinen ja Simon enkelit' in which doctor Jyrä invented a test-tube-adult who looked exactly like Mutikainen, a mathematician. When the test-tube-adult's body emerged, his voice moved into Mutikainen's body because of the doctor's error. Problems ensue.
