In the third installment of the popular In-Laws series, the Chrapek and Wilk families reunite once again, this time at a quiet countryside resort to celebrate their grandson’s christening.
Wanda and Tadeusz organize the celebration, inviting Małgorzata along with her friend, psychotherapist Grażyna. Małgorzata’s ex-husband, Andrzej, also makes an appearance, returning from Australia with new company. As always, the gathering quickly turns into a series of funny and unexpected situations, highlighting the clash of family personalities and traditions.
