Dr. Jakob Feldmann is a renowned German geneticist at Research Hospital Essen... and a recluse par excellence. Ivo Andersson is a male nurse working at the same hospital as Jakob. His outgoing personality and good looks have earned him the nickname Sir Grin-a-lot. They both have a crush on each other that everyone except the two of them seems to know about. But when the German Federal Police shows up with two patients suffering from a suspected alien infection, their voluntary exile in the high security research complex shifts their relationship into fast-forward mode. Just when they find the courage to open up to each other, Jakob discovers the true nature of the infection. He has to make a decision that will change everything. How much can love endure?
