When Palm Springs opens we see Nyles (Andy Samberg) moving around a party acting like a Grade-a idiot. He seems unlikable and not in a good way. Then, as Palm Springs progresses we discover that Nyles is actually stuck in a time loop. He's literally reliving the same wedding day (not his) again and again. He meets Sarah (Cristin Milioti) and things seem to be moving in a totally different direction. Until we realize that Nyles is being hunted by Roy (J.K. Simmons) and then ends up, inadvertently, pulling Sarah into the time loop. They both can remember every day that they've relived while nobody in the wedding party has a clue. Nyles and Sarah's relationship deepens and then, if it's possible, Palm Springs becomes even more interesting.

Clearly one of the most original, time traveling/time loop, romantic comedies in recent memory, Palm Springs is truly the sleeper hit of the summer.
