Produced independently, it is Jardin's feature film debut, and stars Brittany O'Grady, James Morosini, Gavin Leatherwood, Nina Bloomgarden, Alycia Debnam-Carey, Reina Hardesty, Devon Terrell, David Thompson, and Madison Davenport as a group of college friends who reunite for a party eight years after they were last together, only for the night to spin increasingly out of control after one of them offers to play a game involving body swaps.

It received positive reviews, with praise going to its "clever" and "fun" body swapping-concept, style, and performances, although some found the writing overly convoluted or lacking substance.

Also due to attend is their mutual friend Forbes, whom they have not seen since a party in college for which he got expelled for bringing his high school student sister Beatrice.

The millennial generation has grown up obsessed with how they are perceived — online and in-person — and adopting totally new faces with anonymity unleashes their inner animals.

Whereas the similarly eerie millennial send-up Search Party took vicious aim at recognizable tropes, this pack makes an impression as a tight ensemble rather than as compelling individuals.

It veers between being overly simplistic and needlessly chaotic, often sidelining the supporting characters to focus more on the central couple, leaving the rest of the ensemble cast feeling underutilized."

He praised the production values and performances, but felt that "The potential for a more engaging story was there, but it’s overshadowed by a lack of depth and consistency in the character arcs...
