Lisa has accepted the marriage proposal from her Croatian boyfriend Hrvoje and is in seventh heaven. However, the walk down the aisle presents the couple with an unexpected problem. Hrvoje's strict Catholic mother, who insists on a traditional wedding, and Lisa's divorced parents from the former hippie scene are worlds apart. So the bride-to-be tries to persuade her quarrelling parents Gerd and Theresa to pull themselves together during the celebrations in Croatia! Easier said than done, because Theresa is extremely skeptical about her daughter's marriage plans. When she discovers that the groom is apparently seeing someone else, her worst fears seem to be confirmed.
