Dorothy Munford, the owner of the publishing emporium named after herself, organizes the annual family reunion in the hotel that's been hosting it for years and that has earned her trust. Her daughter, her son and his wife, her new boyfriend, and her first husband attend the meeting. Mrs. Munford wants to use the gathering to meet her lawyer and change her will. The young man brings the documents that both Dorothy and her right hand at the company must sign; the latter, as a witness.

Instacrime is a cooperative game system which introduces you to a mystery that needs to be solved by a group of detectives. Each player must describe the contents of their photographs in order to share the information at their disposal with the objective of setting out a joint theory that explains the case.

Each case is unique and unrepeatable, and therefore, it can only be played once.

But don't worry! If you want to make the most of it, let a group of friends play it and have fun listening to their theories.
