When a wealthy patriarch names his son "Jolly" as the sole heir in his will, a motley crew of relatives, swindlers, and impostors converges on a luxury cruise meant to celebrate his birthday. Each claimant adopts the cheerful persona in hopes of securing the fortune, turning the ship into a chaotic stage of mistaken identities, overheard conversations, and escalating pratfalls that spiral into romantic mix-ups and comic showdowns.
Housefull 5 leans into slapstick and screwball energy while finding tender moments amid the bedlam, as loyalties are tested and secrets come ashore. With an ensemble cast delivering rapid-fire gags and warm-hearted performances, the film ultimately trades the chase for a message about the true value of family, identity, and forgiveness.
