Katia and the successful young banker Andrei arrive on Malta for a holiday. In
the diving-centre they meet Max, a professional diver, who is secretly engaged
in illegal archaeology, and is also Katia’s ex.
During one of the dives Katia finds a piece of a life jacket from a German WWII
submarine. She finds out that in 1942, a collection of unique ancient Egyptian
relics was seized from the Maltese order of hospital knights; this collection
should have been delivered to Germany on a submarine. However, the valuable
cargo never arrived.
Figuring out that the submarine with the treasures is most likely at the bottom
of the sea on the Maltese coast, the three begin the search, getting caught up in a
series of dangerous adventures, including under water. The relationship between
the adventurers is more and more reminiscent of a love triangle..
