Gad plays a screenwriter — “I wrote for two seasons on ‘Blue Bloods'” — who ponders who killed somebody and buried them in the walls of the house he grew up in.

His sister is just a tad freaked out by the fact she lost her virginity in that very basement.

A body must be disposed of, blackmail must be faced and a “scary” relative (Anthony Carrigan) must be consulted in this Sept. 19 comic mystery.

Alex Winter of “Bill & Ted” fame directs and co-stars, with Billie Lourd and Chris Candy in the cast for fans of nepo baby actors.

Looks cute, but maybe a hard sell as it has a brief theatrical release followed by VOD a few days later scheduled.
