A serial killer is on the loose and the finger of suspicion points to a bubbly, harmless girl. The whole mystery could be solved if the cop investigating the case could find a missing Sunday.

Director Rohit Shetty’s movie ‘Sunday’ is a comedy film with a good dose of suspense thrown in. The film stars Ajay Devgan, Ayesha Takia, Arshad Warsi, Irrfan Khan and Anjana Sukhani.

Character Sketches:

Ayesha Takia as Seher
She can imitate a thousand different cartoon characters and that's what makes her such a wanted dubbing artiste. Then she finds herself 'wanted' in a different sense altogether – by gangsters, by taxi drivers and by the cops – as a murder suspect.

Ajay Devgan as ACP Rajvir Randhava
He is the brave, bad cop, who loves his ice cream cones as much as he loves chasing criminals. But what he loves most is letting them off for a hefty bribe! Then suddenly Rajvir finds himself embroiled in a murder mystery where the prime suspect is none other that his fiancée - Seher!

Arshad Warsi as Ballu
His red Ambassador taxi is just like him - bright, optimistic and full of beans. He has no hassles about stuffing too many tourists into his taxi or giving a lift to a strange, giggling girl in the middle of the night. What does bug him is when the girl disappears without paying him his fare.

Irrfan Khan as Kumar
Kumar is Ballu's bum chum and budding actor. He can play lawyer, Ravan, Dracula, don at the drop of a hat. But when he meets a girl who claims she's a dead woman, he drops all his acts and scoots like hell.

Storyline:
A dead body found floating in a lake… Unexplained scratch marks on her neck… Supari killers out to kill her… A taxi driver who yells ‘bhoot, bhoot’ every time he sees her.

Seher is at first amused, then mystified and then terrified when she realizes she has a connection with all these totally unconnected incidents. But she cannot remember anything.

Seher’s fiancé Rajvir Randhava is convinced that she is innocent, but he is also equally sure that she is linked to everything. But she cannot remember a goddamn thing.

Then another dead body is found. And the bracelet found near the dead body belongs to Seher. The evidence is mounting and all fingers point towards Seher. And still, she cannot remember a darn thing.

Is Seher really as innocent as she claims to be? Is she a dubbing artiste by day and a serial killer by night? Is her bubbling charm but a mask that hides her darker and menacing self?

As Sehar desperately fights the fog that clouds her treacherous memory, ACP Rajvir has to fight the fact that the woman he wants to marry may well be a murderer and worse.

What if one day went missing from your life?

‘Sunday’ also features cameo appearances by Esha Deol and Tusshar Kapoor.
