简介
[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.
