Danika Delany is loving running her uncle's old fashioned malt shop on eastern Long Island and putting her own modern spin on the treats they serve. Life is finally looking up for her! That is, until local billionaire Maxwell Crumbholtz dies and leaves his fortune in the form of a treasure hunt. Chaos descends on Watchogue, and Dani and the rest of the gang from the Coffee & Cream Café join the melee when they enter the contest, try to decipher the clues, and go in search of the treasure. But Dani digs up more than she expected when she discovers a dead body buried instead of a treasure! To make matters worse, a witness claims to have seen Dani at the scene of the murder. Now, instead of a four-billion-dollar payday, Dani is on the hunt for a killer.
