Summary [PART 1] Founding CEO Jan Ritter and business partner Tanja Wiemer engaged married two study buddies, mountain guide Sabine Haller and expecting father Paul Emerling, a brilliant but acrophobic engineer, to solve on the spot troubles in installing their demo installation of cellphone connections in too high areas by radio transmitter, urgently as a potential buyer is expected. When intoxicated Jan flirts with his ex Sabine roughly, she freaks and falls, apparently fatally, but actually onto a ledge, where Tobias comes rescue her by rope from the helicopter, but panic-deluded she pushes him -seeing only 'rapist' Jan- so they both fall. Tobias is hospitalized, in terror if his paralysis will be temporary, as luckily turns out later. [PART 2] Fearing a murder charge killing the lucrative deal, Jan pretends Sabine just left, but his companions get suspicious and gradually find out, so Jan desperately seeks to cover up, whatever it takes. Andreas's team finds still hysterically-hostile Sabine Haller. Toni finds a link to Paul's pregnant wife Anne Emerling, who inspires them to go look for him, so they find the trio, bickering and ignorant Sabine lives, news with a spectacular impact. Among the interested minor investors are Andreas's ignorant copycat father Franz and Tobias's shrewd Peter.
