15 DAYS is a fast-paced adventure game about Cathryn and her friends, a London based group of young art thieves who are stealing art for good causes, just like modern day Robin Hoods.

In the meantime, US special agent Jack Stern has a murder case to solve. A high ranking politician has died, bleeding from his ears and nose. An assassination has to be considered. During the next two weeks special agent Stern as well as the young thieves will become entangled in an international conspiracy about stolen art and political assassination.

Soon their paths are about to cross, as the game takes the players to many different locations, including the London Eye Ferris wheel, the Catacombs of Paris and an exotic totalitarian island country.
