Kaśka and Jan's wedding day turns chaotic as their families' web of secrets and lies begins to unravel.

Reviewing the series' first episode, Johnny Loftus of Decider wrote, "Family Secrets feels very contemporary with its narrative switchbacks and various tiers of love life damage.

It’ll be interesting to see who’s with who and what has finally been said out loud once this wedding day ends eight episodes from now.

"[1] Molly Hirsch of The Michigan Daily wrote, "While the timelines frequently shift throughout the episode, the plot remains engaging and surprisingly easy to follow.

As a result, the viewer can’t help but want to binge the entire eight-episode series in one sitting.
