Over Tissa (Russian: Над Тиссой, romanized: Nad Tissoy) is a 1958 Soviet spy thriller film directed by Dmitri Vasilyev and based on the eponymous book by Alexander Avdeenko.

Taking off Belogray's military uniform, picking up his documents and covering up the body with stones, the criminal hides.

A little later the enemy agent illegally penetrates the territory of USSR with the task to blow up the railway bridge across the river Tisza (in the film - Tissa), close to the village where Ivan was going.

"Belogray" comes into contact with the local resident Dzyuba and passes Skiban a camera disguised as a cigarette case with orders to take pictures of the approaches to the bridge.

Border guards detain the saboteur, the locals find the real Belogray's body at the pass and bury him near fallen comrades.
